The TBSHT03 is an air humidity and temperature sensor with SDI-12 interface. The sensing elements are located on a replaceable PCB in the tip of the sensor. The acquisition circuit is completely over-moulded. Temperature measurement is carried out with a 0.1°C precision PT1000. Humidity measurement is based on a precision sensing element on a ceramic substrate. The sensor tip is protected with a replaceable filter. Each sensor is individually factory-calibrated. With dimensions of only 100mm x 16mm, the sensor can easily be fitted into many standard radiation shields.
