SenseCAP Wireless LoRaWAN CO2 Sensor AU915/AS923
SenseCAP Wireless CO2 Sensor measures levels of CO2 emission in the atmosphere, designed with an NDIR CO2 sensor and a custom battery. It's dustproof, optimal for use cases that need reliable data collection, even in dusted indoor environments such as chicken farms.
Among the first launch of Seeed industrial IoT (IIoT) product series, SenseCAP is focusing on wireless environmental sensing applications: smart 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 Air Temperature and Humidity Sensor measures temperature and humidity in the atmosphere at the range of -40℃ to 85℃ and 0 to 100 %RH (non-condensing) respectively. With a high-precision measurement chip, this sensor features stability and reliability, making it widely applicable in industrial environmental sensing scenarios.
This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, a 2-in-1 sensor, and a custom battery. It is specifically designed and optimized for use cases powering end devices by batteries for years. To minimize the power consumption, the device wakes up, transmits the collected temperature and humidity data to the gateway, and then goes back to sleep.
Under the best of circumstances, the battery is expected to last for more than 8 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 adopts a modular design, integrating the data-logger with the sensor probe, which can be replaced by other SenseCAP sensor probes. This sensor's data logger is rated IP66, and the sensor probe is rated IP65.
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.
