1、 Introduction to Ammonia Gas Sensor Module Products

The BYG511-NH3 series ammonia gas sensor adopts a standard three electrode electrochemical gas sensor, with output signals such as TTL and IIC. It is designed for low-cost application users of integrators and can be freely integrated. It is widely used in various monitoring and monitoring solutions. It has an intrinsic safety design, can be equipped with electric plug and unplug, simplified peripheral circuits, personalized data calibration and calibration programs, and can freely switch sensor probes (of the same model, so that the sensor life can be freely replaced when it reaches its limit). It also supports oxygen cells, 2pin electrodes and similar packaging, and is perfectly compatible with standard inner diameter explosion-proof detection heads. It is suitable for rapid prototyping monitoring solutions and environmental gas monitoring systems.
