The SenseCAP Wireless Air Temperature & Humidity Sensor measures air temperature and humidity across a wide range of –40℃ to 85℃ and 0 to 100% RH (non‑condensing). Equipped with a high‑precision measurement chip, this sensor delivers excellent stability and reliability, making it ideal for industrial environmental monitoring applications. 🌡️💧
This device integrates a built‑in LoRaWAN® long‑range transmitter based on SX1276, a 2‑in‑1 temperature & humidity sensor, and a custom high‑capacity battery. It is specifically engineered for long‑term, low‑power deployments where end devices operate on batteries for years.
To minimize power consumption, the device wakes up periodically, transmits the collected temperature and humidity data to the gateway, and then returns to sleep mode. Under optimal conditions, the battery life exceeds 8 years, depending on the data transmission interval. Please note that the default interval is once per hour. If you wish to modify the data upload interval, please refer to this document.
The SenseCAP Sensor adopts a modular design, integrating the data logger with the sensor probe, which can be replaced with other SenseCAP probes. The data logger is rated IP66, while the sensor probe is rated IP65. 💧🛡️
About SenseCAP
As part of Seeed’s industrial IoT (IIoT) product line, SenseCAP focuses on wireless environmental sensing applications such as smart agriculture, precision farming, and smart cities. It includes hardware (sensors, data loggers, gateways), software services (SenseCAP Portal, mobile App, dashboards), and APIs for device & data management.
Note
The SenseCAP Sensor is fully compliant with LoRaWAN® specifications and works with any standard LoRaWAN gateway. Please select the appropriate gateway according to the sensor frequency. Seeed also provides the SenseCAP LoRaWAN Gateway for seamless integration without additional provisioning workload.
