　　DigiTHP-GEN2 is an air humidity, temperature and barometric pressure sensor. The sensing elements are located on a PCB in the tip of the sensor. The acquisition circuit is completely over-moulded. Temperature and humidity sesor is based on a precision SENSIRION? sensor. An additional BOSCH?MEMS chip measures barometric pressure. Each sensor is individually factory-calibrated. With dimensions of only 108mm x 16mm, the sensor can easily be fitted into many standard radiation shields and field application.

　　The SDI-12 output provides universal compatibility with any SDI-12-enabled data logger and low power applications, or use a RS485 physical interface for applications that require long cable runs or many sensors.
