LoRaWAN formaldehyde (HCHO) sensor is an IoT wireless sensor developed based on LoRa wireless technology, with built-in formaldehyde sensor and temperature and humidity sensors. It uses electrochemical principles to monitor the concentration, temperature, and humidity of formaldehyde in the environment in real time. This system has the characteristics of high detection accuracy, stable performance, and low power consumption, and is widely used in environmental monitoring, industrial emission monitoring, chemical plants, and other fields.
