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.
