SenseCAP CO2, Temperature and Humidity Sensor with RS485&SDI-12
The CO2, temperature, and humidity sensor supports Modbus-RTU/ASCII RS485 and SDI-12 communication protocols, built-in calibration functionality, and is compact in size, making it widely applicable in greenhouses, cities, poultry farms, transportation stations, and other application scenarios where CO2 level is needed.
PRODUCT DETAILS
The CO2, temperature, and humidity sensor supports Modbus-RTU/ASCII RS485 and SDI-12 communication protocols, built-in calibration functionality, and is compact in size, making it widely applicable in greenhouses, cities, poultry farms, transportation stations, and other application scenarios where CO2 level is needed.
Features
- 3-in-1 sensor: Measure Carbon dioxide(CO2), air temperature, relative humidity
- Wide Range & High Accuracy of CO2: 0ppm ~ 10,000 ppm, ± (40ppm+3%*MV)
- High performance: high accuracy, fast response, and superior stability
- Wide-range Power Supply and 2 protocols: 5V ~ 24V power supply, support RS485(Modbus -RTU / Modbus -ASCII) and SDI-12 protocols
- User-friendly: factory-calibrated, supports custom calibration by pressing keys or using commands, easy to install and integrate
This is a digital CO2 concentration sensor based on NDIR (nondispersive infrared), which can continuously collect and calculate the CO2 concentration in the air per unit volume and output in the form of a universal interface. It's designed to adopt PTFE film combined with a protective enclosure, improving its breathable performance. It is more accurate, stable, reliable, low-power consumption, and user-friendly. It compacts in size and can be easily integrated into various application scenarios.
This digital NDIR CO2 concentration sensor supports RS485(Modbus -RTU / Modbus -ASCII) and SDI-12 communication protocols and is compatible with the wide power supply voltage of 5-24V. It has a built-in calibration functionality and can be widely applied in both indoor and outdoor environments. This product also adopts both single-air-chamber and double-channel. This CO2 Sensor (Version CO2-Connector) comes with a waterproof aviation connector, helping you save time and effort in wiring the sensor to a data logger with screws.
Connect with 4G Sensor Hub or LoRaWAN Data Logger for Remote Transmission
We offer the SenseCAP S2100 - LoRaWAN® Data Logger - Seeed Studio and SenseCAP Sensor Hub 4G Data Logger suitable for SenseCAP ONE series weather sensors, you can transmit the sensor data to public LoRaWAN® network servers(Helium, TTN, etc.,) or private servers.
