WiFi Car Sentry

Low power car monitor and control system

Revision 2

Using the ESP07, it connects with the home WiFi to report information on timer using DeepSleep. Remember to remove the red LED on the ESP to reduce current. This new revision uses a switching regulator for the lowest current possible. It uses about 25mA on, and 39ÂľA in sleep at 12.5V.

I/O peripherals:
OLED (optional for temporary display)
DHT22 for temperature and Rh
0-17V analog voltage reading
2x 1-40V digital input (for sensing if something is on)
3x sink inputs (alarm or sensor)
3 sink outputs for controlling relays, etc (the bom has 7.6A MOSFETs)
Plus extra O/I for GPS or other sensors. The outputs can be used to switch them off for more power saving.
