I just want to update everyone with the latest improvement on the Environment sensor.
In this iteration, I am trying to improve the power management system. It is important for the sensor to be able to operate during short power outage especially since it is double up as a repeater. For those who has Xiaomi devices, one may want to keep them as a child of this sensor.
Here is the new board will look like.
It is a bit bigger compare to previous board to accommodate charging circuit.
I am not finish testing this feature. There are a couple parts that still need to be installed. I have started testing with common toy lipo battery.
This power management is unique for this type of sensor compared to what is available in the market. A lot of DC or AC powered sensor/devices which ac as repeater do not have battery backup. In the event of power outage, the battery power the sensor automatically.
I am still in the process of testing the power management and making adjustment. I will update again when I am close to have something to share.
