Its tasks include reading the solar panel and battery voltages, and PIR output. When movement is detected by the sensor, it activates a clever little latching power circuit to power on the ESP01 ...

The weak signal from the PIR sensor will be amplified by the first two op-amp configured as amplifiers, the amplified signal is then fed to the last two op-amp configured as comparator. The BC548 NPN ...

A four-pack of Aootek Solar Motion Sensor Lights is just $20 ahead of Amazon's Big Spring Sale. Shoppers say they work “flawlessly and are “worth every penny.” ...
