SM400D2MOD 7-in-1 Air Quality Sensor Module RS485 Output for CH2O Temp Humidity CO2 TVOC PM2.5 PM10
Description:
SM400D2MOD is a cost-effective 7-in-1 sensor module. The module supports a wide operating voltage and digital MODBUS-RTU protocol output. It is a digital serial output sensor module with multiple protections. It supports two output modes, namely RS485 data bus and UART serial TTL level.
It integrates CO2, CH2O, TVOC, laser PM2.5, PM10, temperature and humidity detection. It can carry out real-time and comprehensive detection of the environment. Furthermore, the module also has good stability, making it convenient for customers to use.
Features:
- Working voltage: 5V-32V for RS485 interface and 5V for UART interface
- With anti-reverse polarity protection for power supply, short circuit protection for RS485 signal line, overload, over-voltage, over-current and lightning protection
- RS485 bus transmission and standard MODBUS-RTU protocol make it convenient for customers to use
- Monitoring data is transmitted in the question-and-answer mode, and the data is read as needed
- Sensor address can be reset, and multiple sensors can be used on one RS485 bus
- Seven sets of data, including CO2, CH2O, TVOC, PM2.5, PM10, temperature and humidity, can be output at the same time. High sensitivity and stable data are enabled
- The seven sets of monitoring data are automatically output through the RS485 interface every second
- RS485 bus and UART TTL level output modes make it convenient for customers to choose and use independently
- Accurate to 0.1°C for temperature and 0.1% for humidity
Applications:
- Hotel room air quality monitoring
- Environmental monitoring of agricultural greenhouses and outdoor breeding sites
- Fresh air ventilation system
- Air purifier and air conditioner
- Air quality monitoring equipment
- Kitchen and bathroom ventilation control system
- Smart home devices
Package Included:
- 1 x Sensor Module
Packaging Details:
- G.W.: 0.15kg
