About SenseCAP

Among the first launch of Seeed industrial IoT (IIoT) product series, SenseCAP is focusing on wireless environmental sensing applications: smart “https://solution.seeedstudio.com”agriculture, precision farming, and smart city, to name a few. It consists of hardware products (sensors, data-loggers & gateways, etc.), software services (SenseCAP portal, mobile App, open dashboard), and API for device & data management. SenseCAP supports different communication protocols, such as LoRa, 2G, 4G, NB-IoT, and more.


SenseCAP Wireless CO2 Sensor measures the level of carbon dioxide (CO2) gas at the range of 0 ~ 40000 ppm in the atmosphere, applicable for indoor environments. It is perfect for monitoring CO2 ppm in greenhouses, industrial campuses, factories, schools, office buildings, hotels, hospitals, transportation stations, and anywhere that data of CO2 emission is needed.

This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, an NDIR CO2 sensor, and a custom battery. It is specifically designed and optimized for use cases powering end devices by batteries over the years. To minimize the power consumption, the device wakes up, transmits the collected CO2 data to the gateway, and then goes back to sleep.

Under the best of circumstances, the battery is expected to last for 1.5 years, depending on the data transmission intervals. Please kindly note that the default interval is once per hour. If you’d like to change the data upload interval, please refer to this document.

SenseCAP Sensor Node adopts a modular design, integrating the data logger with the sensor probe, which is replaceable by other SenseCAP sensor probes.

The data logger part is designed with industry standards and equipped with an IP66 waterproof enclosure. To ensure accuracy and sensitivity, we chose the material with the optimal breathable aperture for the sensor probe, which however is not waterproof. Hence, this CO2 Sensor is applicable only for indoor environments. The product is dustproof, making it ideal for environments such as chicken farms, where there is poultry dust.

SenseCAP Sensor is fully compliant with LoRaWAN specifications and can be used with standard LoRaWAN gateways. Please choose the corresponding gateway according to the sensor frequency. Seeed also provides SenseCAP LoRaWAN Gateway (coming soon) for you to use with SenseCAP Sensors seamlessly without extra huge workload for provisioning.
