Introduction
The carbon dioxide sensor is an industrial-grade sensor with high integration. The data is sent from the internal chip of the probe to the computer through the modbus-RS485 interface, and multiple probes can be connected to the bus network to realize real-time monitoring of multiple field environments. It has super stability and anti-interference ability, strong product protection performance and first grade lightning protection, which can be used in agricultural industry and other occasions.
Use Case Scenarios It is widely used in agricultural greenhouses, intelligent buildings, workshops, warehouses, pharmacies, libraries, museums, laboratories, offices, ventilation ducts and other places where carbon dioxide concentration needs to be monitored.
Features High precision, wide range, good consistency. Standard audio interface design, easy to plug. Super stability and anti-interference. The product has strong protective performance and first grade lightning protection.
