Wiring Method
Q1: What parameters can this indoor air quality sensor with WiFi/RS485 output measure?
A1: This indoor air quality sensor with WiFi/RS485 output simultaneously monitors temperature, humidity, PM2.5, PM10, TVOC, CO2, and formaldehyde (CH2O), covering the core indicators for comprehensive indoor air quality assessment.
Q2: What are the differences between WiFi and RS485 output on this indoor air quality sensor?
A2: The RS485 output on this indoor air quality sensor uses the Modbus-RTU protocol, enabling stable long-distance transmission and direct integration with building automation and industrial control systems. The WiFi output eliminates the need for communication cables, allowing the sensor to connect wirelessly to a network for remote data access via a computer or mobile device.
Q3: What power supply does this indoor air quality sensor with WiFi/RS485 output require?
A3: This indoor air quality sensor with WiFi/RS485 output accepts a wide DC 10-30V input and consumes only 1.5W, making it compatible with most standard power supply configurations.
Tips: How to ensure accurate readings from this indoor air quality sensor with WiFi/RS485 output?
- Place the sensor at least 1.5 meters above the floor and away from doors, windows, air vents, or direct sunlight to avoid external interference.
- Avoid installing the sensor near heat sources, steam outlets, or areas with strong airflow, as these conditions may affect temperature, humidity, and gas concentration readings.
- Allow the sensor to warm up for at least 10 minutes after power-on before recording data, ensuring the sensing elements reach optimal operating stability.
- Clean the sensor housing and ventilation openings regularly to prevent dust accumulation, which can impact gas detection sensitivity and overall measurement accuracy.
