Precipitation; Relative Humidity And Temperature; Back Of Module Temperature Sensor - RainWise PVmet 500 Series User Manual

RAINFALL / PRECIPITATION SENSOR
There are two terminals on the main board for an optional rain gauge. The PVmet-500 is compatible with any 0.2mm tipping bucket
rain gauge that uses a normally open switch contact. The inputs are not polarity sensitive.
RELATIVE HUMIDITY AND TEMPERATURE SENSOR
The relative humidity/temperature sensor is pre-installed at the factory. The sensor is precisely placed within the tube putting the
sensor in-line with holes to allow adequate air flow. If the sensor requires replacement, separate the top mast from the middle mast
while feeding a little cable up through the hole under the enclosure.
The temperature sensor is mounted on a long thin PCB board that has ears for locating it in the proper position within the temperature
shield stack. Because the sensor is exposed to moisture and dust the cable is terminated on the board and completely sealed so the
cable and sensor are changed as a unit. It can be difficult to get the new cable feed through the mast then up through the hole below
the enclosure so attaching a tagline to the old sensor before removing it will make installation of the new sensor easier.
