Integrating sensors into a photovoltaicsystem allows additional measurments to be recorded, such as Irradiance, Ambient Temperature and much more.
SEVEN Sensor Solutions, as a weather station supplier, provide 3 types of ambient temperature sensors : Ambient Temperature sensor with Digital Output, With Analog Output and a third with Modbus RTU Output.
DIGITAL AMBIENT TEMPERATURE SENSOR BY SEVEN SENSOR SOLUTIONS
The Ambient Temperature Sensor must never receive light directly from the sun and must be mounted in a radiation shield, as it has the ability to protect the sensor from the effects of radiation. Therfore, SEVEN’s Ambient Temperature Sensor, with Digital Output DS18B20, is proctected by an IP65 plastic shield,
UV and weather resistant, with 4 plates that allow air to pass freely and protect the sensor from any source of radiation. The measuring range is between -55°C and 125°C.
CHOICE OF AMBIENT TEMPERATURE SENSOR LOCATION
Most commom installation errors in weather stations are associated with incorrect positioning of the temperature sensor. When placing a weather station, make sure:
- The Ambient Temperature Sensor never receives direct sunlight and is mounted in a sheild for protection.
- The Ambient Temperature Sensor is well ventilated by the wind and not blocked.
- The Ambient Temperature Sensor should be located 15 meters from the nearest paved surface.
- The Ambient temperature sensor must be installed in shadow (even if it’s mounted in shield).
USE OF AMBIENT TEMPERATURE SENSORS
The DS18B20 Digital SEVEN Ambient Temperature sensor is used for Huawei weather stations; we have obtained Huawei’s approval for our entire weather station which includes the Modbus RTU Irradiance sensor 3S-IS-T-MB, Wind Speed Sensor 3S-WS-PLS-B, Wind Direction Sensor 3S-WD-I/U, Ambient Temperature Sensor 3S-AT-18B20 and Module Temperature Sensor 3S-MT-18B20. IT is also used for GoodWe, Growatt and Sungrow stations as it is compatible with Ezlogger, Shinemaster and Sungrow logger. You can visit our website for more information about our sensors and other types of Ambient Temperature Sensors, Analog and Modbus RTU, which are compatible with other well-known brands such as Kaco, SMA, SolarEdge, etc.
Our engineers, as part of SEVEN Sensor Solutions, are available to assist customers with remote setup service and information on anything that may need.
