Zigbee Carbon Dioxide Sensor 1.detect indoor air quality 2.can measure C02, temperature, humidity and VOC
This item of product is used especially to detect indoor air quality.To fix it in bedroom can detect related C02,temperature, humidity,VOC level and control devices to ensure excellent living condition.
Main Features
Detect indoor air temperature including C02,temperature, humidity and VOC
Small size and cheap price
Can auto control devices such as air-conditioner etc
Production Description
Transmitter can be used to measure indoor air quality. To fix it in bedroom can measure C02,temperature,humidity and VOC level in air and auto control and purify ventilation device to ensure excellent indoor living condition. It can be also mounted in ventilation system which has been existed or ready for installation by lower costs.
Transmitter integrates 4 sensors, which can measure C02, temperature, humidity and VOC at the same time. It has small size and cheap price. By RS485 and RS232 port output,it can measure data,monitor air quality differeces in the air to realize intelligently control air-conditioner,humidification and other ventilation devices.
