ES-S320 Ultraviolet UV sensor

ES-S320 UV sensor is based on the principle that photosensitive elements convert UV rays into measurable electrical signals to achieve online monitoring of UV rays.

ES-S320 UV sensor is based on the principle that photosensitive elements convert UV rays into measurable electrical signals to achieve online monitoring of UV rays. The circuit uses industrial-grade microprocessor chips imported from the United States and imported high-precision UV sensors to ensure the product’s excellent reliability and high precision. The product housing is a wall-mounted high-protection grade housing with a protection grade of IP65, which is rain and snow proof.

The product integrates temperature and humidity sensors into one, and the measurement data is more comprehensive. The product outputs 485 signals (standard Modbus-RTU protocol), can communicate up to 2000 meters, and supports secondary development.
