RAK7204 | Your No Fuss Indoor Weather Station

One of the most herculean task is getting to monitor your microclimate. Environment is an important factor in human survival. So, getting to read this piece will open your eyes to the easiest way to monitor your microclimate and ensure your convenience.

The environment has become a germane yardstick of survival for every existing species. And its close monitoring is equally important as it helps you and me to better manage the environment.

Monitoring the environmental conditions is not a simple task. Neither is it a trivial act that can be done just by anyone. That's the reason behind the production of RAKwireless' RAK7204. Taking the weather conditions into cognizance, RAK7204 will help in making weather monitoring an easy task.


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

RAK7204 is built-around a low-power MCU and low-power sensors, and the firmware has been optimized for efficiency, it can achieve a very low-power operation in both dormancy and when measuring and transmitting.

One of the most prominent features of the devices is the long-lasting battery. The battery that comes with RAK7204 is non-rechargeable and can last more than 2 years. Naturally the battery level is reported in regular intervals, and upon reaching a critical level an alarm is activated, thus you will never be surprised by a sudden power loss of your device. Naturally, the design allows for replacing the battery, so even after those 2 year are up, you can still refresh your node for another 2 years of operation.

The installed firmware makes it possible for you to toggle the sampling intervals of the sensors and the transmission cycle. This gives you a range of configuration options, so based on your preferred settings you can either optimize for battery life or data granularity. We would recommend striking a balance, so you still have a long operation time, but not at the expense of sacrificing too many data samples.

Lastly, the RAK7204 adopts a highly integrated design. The environmental sensors, LoRa transceiver module, LoRa antenna, and the battery are fitted in a 90x85mm sized housing. These small dimensions allow for installation in tight spaces or ones that require the sensor to have a minimal impact on the overall feel of the surrounding environment. The housing adopts a hollow, permeable design to facilitate air flow that will increase the accuracy in the detection of changes in the environment.

In summary these are some of the features and major selling points of this powerful, yet compact LoRaWAN weather station.
