Archive (EOL) TBSHT02 SDI-12 Air Temperature / Humidity Probe

The TBSHT02 is an air humidity and temperature sensor with SDI-12 interface. The sensor uses a single chip sensor element which measures both temperature and air humidity.
Each sensor chip is individually factory-calibrated.
The sensor chip is protected with a PBT filter cap carrying a PTFE membrane with 1.5µm pore size.
The TBSHT02 Board provides through holes for the connection of a SDI-12 interface cable.
The sensor including bend protection has a length of 115mm and a diameter of 12mm.
The sensor optionally can be supplied as board, without housing and cables.
With dimensions of only 70mm x 8.5mm, the board can easily be fitted in many standard sensor housings.

The TBSHT02 is end of life and has been replaced by our TBSHT06.
