SKU
114991730
SenseCAP Wireless Air Temperature and Humidity Sensor measures temperature and humidity in the 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.
PRODUCT DETAILS
Product Upgrades
We have an upgraded version, please refer to SenseCAP S210X.
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 Long Range 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.
About SenseCAP
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), an API for device & data management.
Note
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 for you to use with SenseCAP Sensors seamlessly without an extra huge workload for provisioning.
