Temperature - Humidity - Air Pressure RAK7204

overview

The RAK7204 is a LoRaWAN node with integrated environmental sensors. The high-precision environmental sensors can measure changes in temperature, humidity and gas pressure and provide an indoor air quality index. All collected data can be sent to a LoRaWAN gateway to be forwarded to the cloud.

Because the RAK7204 revolves around a low-power MCU and low-power sensors, and the firmware is optimized for efficiency, it can achieve very low-power operation both when idle and when measuring and transmitting. The non-rechargeable battery that comes with the device can last for more than 2 years. With the ability to report battery status regularly and raise an alarm when critical levels are reached, you can be sure that you will never be caught off guard and your device will not be ready to use when you need it most. In addition, the battery is still replaceable, so even after those two years have passed, you can refresh your node for another two years of operation.

The firmware has built-in functionality that allows the user to set the sensor sampling interval and transmission cycle. This allows flexibility as one can choose whether to take more accurate measurements at the expense of battery life or extend the operating time by trading the volume of data generated.

Last but not least, the RAK7204 features a highly integrated design. The environmental sensors, LoRa transceiver module, LoRa antenna and battery are housed in a 90mm x 85mm x 34mm package. These small dimensions allow it to be installed in tight spaces or in rooms where the sensor needs to have minimal impact on the overall feel of the environment. The package is hollow and permeable to facilitate airflow and sense environmental changes more accurately.
