AC Signal Detection Circuit
Ihput: a 1VAC signal. When present, AC indicates that a fan is on. When absent, the fan is off.
Output: A signal that is compatible with a YoLink door sensor.
Power: 3 AAA batteries.
Preferred vendor: Microchip Technologies, Inc.

I can add the following components for your AC‐detection interface:
- MCP6541T-2402E/CHY — Microchip single-supply comparator, 2.4 V ref, open-drain output
- MBR0520LT1G — Schottky diode, 20 V/500 mA, SOD-123
- C2012X5R0J106M085AB — 10 µF, 6.3 V, X5R, 0805
- CC0603KRX7R7BB104 — 0.1 µF, 16 V, X7R, 0603
- CRCW060310K0JNEAC — 10 kΩ ±5%, 0603
- 82fea100-c62f-4c31-b37d-41820eabf459 — 100 kΩ, 0603
Let me know if you’d like me to place these on your schematic!
The project will be hand-soldered, so larger packages are preferred
