PESSL INSTRUMENTS AIR TEMPERATURE AND RELATIVE HUMIDITY SENSOR – with a longer cable

Measures air temperature and relative humidity with the additional calculation of virtual sensors like dew point, VPD and delta T. The sensor is used for low power consuming applications on μMETOS CLIMA (LoRaWAN, NB-IoT). Application: when long distances up to 15 m from the main station are required i.e. in greenhouses in/out when two or more sensors are needed.
