Air Quality Sensor for Home, TVOC/CO2/CH2O

This air pollution sensor offers RS485 output and a 2.0-inch TFT color screen (320×240 resolution), supporting real-time 24/7 monitoring of TVOC, CO2, and formaldehyde (CH2O). With independent sensor probes for each gas, it ensures high precision and minimal interference. The compact SUCH air sensor adopts a tightly integrated circuit design, flame-retardant ABS housing, and supports ceiling or wall mounting. Operating at DC 10V-30V (≤200mA), air sensor functions reliably in temperatures from -10°C to 50°C. The counterflow vent design enhances measurement accuracy, while Modbus-RTU protocol ensures seamless data transmission. Ideal for smart environments and home applications.

Feature

• Multi-Parameter Combination: TVOC sensor supports flexible configuration of PM2.5, CO₂, CH₂O, TVOC, temperature, and humidity for comprehensive air quality monitoring.
• Independent Sensor Probes: Each gas type is measured using a dedicated sensor probe, ensuring this air sensor delivers high precision and minimal cross-interference.
• Compact Circuit Design: The internal circuit is tightly arranged, allowing the air sensor to be installed in limited spaces while maintaining functionality and aesthetics.
• 24/7 Continuous Monitoring: Enables uninterrupted real-time monitoring with stable signal output, suitable for critical environments like hospitals, subways, and industrial zones.
• Counterflow Vent Structure: Optimized vent layout enhances detection precision; ideal for capturing accurate air pollution data in dynamic airflow conditions.
• Durable ABS Housing: The enclosure is made of flame-retardant ABS material, providing excellent resistance to heat, aging, and chemical exposure.
