Power Outage Sensor

Power Outage Sensor

Track the 230 VAC power line with your favorite HW using a small, efficient, and inexpensive circuit. In my wireless doorbell tutorial I gave the advice about how to get a digital signal from a 12 Vac source so it could be read with any desired HW. That solution is not valid for high voltage, since the
