Barometric pressure sensor TBSHTP04

membranePCBPTFE

The TBSHTP04 is an air humidity, temperature and barometric pressure sensor with SDI-12 interface. The sensor uses a single chip sensor element which measures both temperature and air humidity. An additional MEMS chip measures barometric pressure. Each sensor chip is individually factory-calibrated. The RHT sensor chip is protected with a PBT filter cap carrying a PTFE membrane with 1.5µm pore size. The TBSHTP04 PCB assembly is silicon casted inside the sensor housing. An additional filter provides dust and insect protection. The sensor has a length of 100mm and a diameter of 16mm. The sensor can be supplied as air temperature / relative humidity variant with part number TBSHT04 or as temperature / relative air humidity /barometric pressure sensor with part number TBSHTP04. The TBSHTP04 is end of life and has been replaced by our TBSHT06.
