The YGC-BG-M Wall-Mounted Multi-in-One Sensor is an integrated device designed to measure illuminance, temperature, humidity, and CO₂. Housed in a rugged IP65-rated enclosure, it offers excellent protection against rain and snow while featuring a breathable membrane to prevent internal condensation.
Equipped with a US-imported industrial-grade microprocessor and a Swiss-made high-precision temperature/humidity sensor, the device ensures outstanding reliability, high accuracy, and probe interchangeability without recalibration.
The sensor supports RS485/RS232 interfaces and the standard Modbus protocol, enabling seamless integration with data acquisition systems. Additionally, it provides up to four analog outputs (current and voltage). The digital output supports both standard Modbus and ASCII protocols, with an open structure for custom programming. It is highly stable, reliable, and easy to install.
