Exciting News: Only 50 kits! Enjoy a 50% discount on our 4G or LoRaWAN® Solution Kits - first come, first served! ●4G Solution Kit ●LoRaWAN® Solution Kit 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. Applications Smart Agriculture Smart Cities Industry and Building ventilation systems Airport, train station, shopping mall, home, office, classroom, and others public places for air quality measurement and indication Lab, warehouse, and other places to monitor the CO2 level Specifications Basic Parameters Product Model S-CO2-03A / S-CO2-03B Supply Voltage 5 ~ 24 V Supporting Protocols Modbus -RTU RS485/ Modbus -ASCII RS485/ SDI-12 (v1.4) IP Rating IP65 (shading measures are required for outdoor installation, and the equipment cannot be exposed to direct sunlight and rainwater for a long time) Operating Temperature 0°C ~ +50°C (Due to CO2 sensor limitations) Working Humidity 0 ~ 95 %RH (no condensation) Cable Length 2 meters Measurement Parameters Range Accuracy Resolution Carbon Dioxide 0 ~ 10000ppm ±(50ppm+3%*MV） 1ppm Air Temperature -40~85°C ±0.2℃ 0.01°C Air Humidity 0~100%RH ±1.8%RH 0.01%RH Wiring Diagram and Calibration Button Sensor onboard a switch and a button: Switch: select protocols(RS485/SDI-12), default is RS485.
