Figaro has two semiconductor type air quality sensors. TGS2600 has high sensitivity to various gaseous air contaminents such as the gases found in cigarette smoke, while TGS2602 shows good sensitivity to volatile organic compounds (VOCs) and odorous gases (such as H2S). By combining these sensors with signal processing, the TGS260x series can be interfaced with ventilation and air conditioning systems to protect the air that you breathe.
TGS2600 - Gas sensor for general air contaminants
This sensor has high sensitivity to various gaseous air contaminents such as those found in cigarette smoke. It is ideally suited for the detection of the gases found in cigarette smoke and for usage in devices such as air purifiers and air conditioning systems. Compared with competing MOS sensors, TGS2600 has a longer useful life and is less costly.
TGS2602 - VOC sensor
With ultra high sensitivity to volatile organic compounds and odorous gases which can be noxious as well as presenting a variety of health hazards, TGS2602 is designed for usage in VOC monitors as well as devices for automating ventilation and air conditioning. Compared to photo ionization sensors, TGS2602 delivers higher sensitivity with longer life and lower cost.

The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater.
In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
The TGS 2620 has high sensitivity to the vapors of organic solvents as well as other volatile vapors. It also has sensitivity to a variety of combustible gases such as carbon monoxide, making it a good general purpose sensor.
Due to miniaturization of the sensing chip, TGS 2620 requires a heater current of only 42mA and the device is housed in a standard TO-5 package.

The sensing element of TGS826 is a metal oxide semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
The TGS826 has high sensitivity to ammonia gas. The sensor can detect concentrations as low as 30ppm in the air and is ideally suited to critical safety-related applications such as the detection of ammonia leaks in refrigeration systems and ammonia detection in the agricultural field.

Circuitry
A transducer is available from Synkera to operate the sensor. This circuit,
packaged on a 2" x 1.5" printed circuit board, is powered with 9 - 24 VDC. The transducer provides a 0 - 5 VDC output which can be adjusted for sensor offset and gain. The heater voltage is also adjustable. The circuit is set to the
recommended values at the factory.
Basic Measuring Circuit
The sensor can be operated using a simple voltage divider. This requires two voltage supplies: heater voltage (VH) and circuit voltage (VC). VH is applied to the heater in order to maintain a constant, elevated temperature, for optimum sensing.
VC is applied to allow a measurement of the output voltage (Vout) across a load resistor (RL).

TGS 3870 is Figaro's new metal oxide semiconductor gas sensor for the detection of both methane and carbon monoxide. Using a micro-bead gas sensing structure, both methane and carbon monoxide can be detected with a single sensor element by periodic application of two different heater voltages (high and low). Miniaturization of the gas sensing bead results in a heater power consumption of only 38mW (average).
TGS 3870 has low sensitivity to alcohol vapors (a typical interference gas in the residential environment) and has high durability, making the sensor ideal for consumer market gas alarms.

In addition, the sensor also has wide application in recreational vehicle and marine applications where durability against severe environmental conditions is required.
TGS2611 - Methane gas sensor
TGS2611 has established itself in the methane detection marketplace for more than 10 years. With superior durability against poisons and interferent gases when compared to competing pellistor type sensors, this sensor has found wide application in gas detectors for residential and industrial usage, portable leak detectors, as well as in natural gas vehicles where severe environmental conditions are encountered.

The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
The TGS 832 has high sensitivity to R-134a, the most promising alternative to R-12, commonly used in air conditioning systems and refrigerators. R-12 and R-22 are also detectable by TGS 832. With its good long term stability, TGS 832 is an excellent, low-cost sensor for CFC detection.

TGS821 Semiconductor type
Figaro semiconductor type sensor TGS821 has high sensitivity to low concentrations of hydrogen. Even at 100ppm of hydrogen, the sensor can detect the target gas with good repeatability and long term stability. Figaro's unique sensor technology makes this sensor highly selective to hydrogen. TGS821 utilizes a durable ceramic housing that makes it ideal for industrial applications which involve transformer maintenance or usage of batteries. This sensor is also appropriate for checking gas leakage within a fuel cell system.
TGS6812 Catalytic type
Figaro's catalytic type sensor TGS6812 can detect levels of hydrogen up to 100%LEL. This sensor features high accuracy, good durability and stability, quick response, and linear output. This sensor can detect not only hydrogen but also methane and LP gas, making it an excellent solution for monitoring gas leakage from stationary fuel cell systems which use hydrogen that is transformed by combustible gases. Due to an adsorbent inside its sensor cap, the cross sensitivity of TGS6812 to alcohol is much smaller than can be found in traditional catalytic type sensors. In addition, TGS6812 is more durable against silicone compounds than the traditional catalytic type sensors.

Description:
As a precision CMOS temperature sensor, the FM20 is cost-effective for accurate low-power temperature monitoring applications. Output voltage versus temperature is extremely linear. With no load, the supply current is
typically 1µA. For normal operation, the load on V OUT should be 5MOhm
or less.
In a typical application, a remotely mounted FM20 is monitored by a microcontroller with an analog A/D converter input. Alternatively, the FM20 can drive a comparator with a high impedance input.
Accuracy is typically ±0.5°C at room temperature, and better than ±2°C from 0 to 75°C.
FM50 is available in a 3-pin SOT-23 package.
Features
- Analog Output: 10mV/°C
- Range: -40 to 125°C Range

INFICON Stiletto® is a scanning-laser particle detection system that finds yield-limiting particle contamination in real time on every wafer. Its increased particle detection area and accurate particle counting and sizing, enable yield and productivity improvements for the most advanced semiconductor processes.
INFICON Stiletto is capable of in situ metrology and process control, enabling yield and productivity improvements for the most advanced semiconductor processes. Stiletto is the first in situ particle monitoring system to be fully integrated with the process tool. When combined with parametric tool data, particle counts can be overlaid with equipment status to allow engineers to identify the exact time and cause of particle formation. The ability of INFICON Stiletto to detect particles during every run of every wafer provides unprecedented protection against defect-induced yield loss.
INFICON Stiletto resonant scanner continuously monitors a much larger volume than the stationary laser beam systems used in existing in situ particle monitors, so Stiletto is able to provide statistically significant count rates for process control. In addition, repeatedly scanning the same volume permits auto-correlation, an advanced signal processing technique that virtually eliminates false counts. This combination of cutting-edge technologies delivers submicron sensitivity that detects "killer particles" while avoiding nuisance events. So you get reliable fault detection for every wafer, every run, every time.
