  • 1. Product overview

    Air temperature and humidity, infrared CO2, dust concentration (PM2.5/PM10), TVOC, CH2O, O3 transmitters are equipped with MEMS special modules to measure air temperature and humidity; at the same time, CO2 sensor data can also be accurately measured based on NDIR principle; PM2. 5/PM10 module provides laser light source and photoelectric receiver. The laser irradiates the airborne particles to generate scattering, and at the same time receives the scattered light at a certain angle, and obtains the curve of the scattered light intensity with time. ) and weight (ug/L), output PM1.0, PM2.5, PM10 three different ranges of particulate matter volume concentration or mass concentration data through serial port; formaldehyde probe is fuel cell type, 2-electrode measurement method, very low power consumption , Good linearity, strong anti-interference ability, can accurately measure PPM level formaldehyde concentration. The O3 probe adopts the principle of electrochemical measurement, with extremely low power consumption, good linearity, high sensitivity and stability, and can accurately measure the PPM level O3 concentration. TVOC adopts imported semiconductor measuring probes, which can measure gas concentrations above 0.01PPM, especially for formaldehyde, benzene, toluene and other volatile gases that have a greater impact on the human body, and can be used for qualitative measurement of air quality.LoRaWAN wireless communication technology star-shaped network, taking into account the design of communication distance, anti-interference, low power consumption, etc., to ensure that the communication distance is longer and the penetration ability is stronger (5~12 floors, 2~6KM field barrier-free communication distance), Compatible with the standard LoraWAN protocol, the networking is flexible and convenient, and it is more suitable for obstacles or indoor applications. It can be widely used in agricultural greenhouses, nursery flowers, smart farming, smart homes, smart commercial buildings, smart transportation and other environmental monitoring fields of the Internet of Things.

    Applicable places: indoor, car, warehouse, factory, environmental protection.

    Indicators, shells and communication methods can be customized.
