Thanks to its compact size and multiple mounting methods, the sensor fits into tight spaces and can be fixed to masts, walls  and  other  constructions.  SRH1A  is  suitable  for installation with a radiation shield which protects the sensor against  water,  dust  and  direct  solar  radiation.  Apart  from standard 1m cable, other cable lengths are available.

The  sensor  is  equipped  with  an  SDI-12  output  and  iscompatible  with  all  data  loggers  using  this  communication standard. SDI-12  (Serial  Digital  Interface  at  1200  baud)  is  a  serial communications    protocol    used    in    environmental measurements. The operating principle is that only an SDI-compatible device with the digital addressing system will communicate with a the pre-configured sensors. Unless  the  sensor  has  a  matching  configuration,  it will  not respond  and  stay  in  a  sleep  mode.  SDI-12  sensors  have  a three wire connection.

The  sensor  should  be  installed  in  such  position  to prevent water from entering. It will not damage the sensor, however the dew formed on the sensor will distort the readings until the water on the filter and sensing element dries up.  Capacitive  sensitive  element  from  the  sensor  can  becalibrated if required with the use of specialist equipment.
