Product Description

     The smoke concentration transmitter designed by our company utilizes a semiconductor-based smoke sensor, offering fast response, high sensitivity, and strong anti-interference capabilities. It features unique compensation algorithms and multi-segment standard gas calibration, ensuring long life, high precision, excellent repeatability, and superior stability. It is suitable for applications requiring real-time smoke concentration monitoring, such as smart homes, intelligent transportation systems, garages, workshops, chemical plants, greenhouse farms, and enclosed living spaces. The device operates on a wide voltage range of 10-30V DC, outputs 485 signals, and supports the standard ModBus-RTU communication protocol. The ModBus address can be configured, the baud rate can be adjusted, and the communication distance can reach up to 2000 meters
