SenseCAP Wireless LoRaWAN Air Temperature and Humidity Sensor
SenseCAP Wireless LoRaWAN Air Temperature and Humidity Sensor AU915/AS923
SenseCAP Wireless Air Temperature and Humidity Sensor measures temperature and humidity in atmosphere. It's designed with a 2-in-1 sensor, a custom battery and an IP66 enclosure, optimized for outdoor use cases that need reliable data collection over years.
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.
