SenseCAP RS485 & SDI-12 CO2 Temperature and Humidity Sensor

The SenseCAP RS485 & SDI-12 CO2 Temperature and Humidity Sensor offers precise and reliable monitoring of CO2 concentration, temperature, and humidity. The sensor uses NDIR technology to measure CO2 accurately and is ideal for real-time monitoring in a variety of environments. Thanks to its support for RS485 (Modbus-RTU/ASCII) and SDI-12 communication protocols and a wide power supply range of 5 to 24V, the sensor is versatile and easy to integrate into existing systems. Its compact design and easy installation make it particularly user-friendly. It is suitable for measuring air quality in public spaces, greenhouses, or urban environments. Additionally, the sensor is IP65 certified and can also be used outdoors, but precautions should be taken against direct sunlight and rain. Calibration can be done by simply pressing a button, which further simplifies operation. This sensor is an excellent choice for those who value high accuracy and reliability.
