Welcome to our shop! This Infrared Carbon Dioxide Sensor is a high precise and durable product with a long life span. It is designed with a small size and low power consumption, making it very practical and efficient. The sensor is an expansion type specifically designed for incubators, providing accurate and sensitive measurements. Made with professional manufacturing, this sensor ensures stable performance and high reliability. It is made of aluminium alloy and comes in a color as shown in the picture. The weight of the sensor is approximately 6g. This CO2 sensor module is widely used in high-concentration environments such as carbon dioxide incubators and analyzers. It has a measuring range of 400-2000ppm with a measurement accuracy of ±40ppm±3% of reading. The working humidity range is 0-85%RH non-condensing. The power supply required for this sensor is 4.5-5.25VDC, with a maximum power consumption of 300mA and an average of less than 18mA. It supports serial communication through UART, compatible with Modbus protocol. The PWM output ranges from 0-100% duty cycle, corresponding to 0-2000ppm CO2 concentration. 100% Satisfaction: Our customers are our top priority.
