WiFi Car Sentry This uses DeepSleep mode to wake up on an interval and send data to another computer or server. Data includes car battery voltage, temperature/rh, a +12V signal, and a negative/sink. 2 sink outputs. There's a pad for the wake pin (sink), which could probably be connected to the alarm. The serial may also be used later for expansion. |

A curious wireless data acquisition project. A USB break-out-board is used to monitor RF transmitters (around $2-$3 for these TX/RX pairs), along with a 4 digit display doing the same. Sensor boards transmit a unique ID plus data and checksum periodically or when triggered, and can run off 3-12V. Coin cells, AA, N cell. Range appears to be 30m at 3V to 600m at 12V. 12 months on a single 14500, except for the ultrasound device. The ultrasound unit was made to detect vehicles. Temp/humidity is used next to the HVAC thermostat. Reed switch on garage door. 3 CDS cell on 3 lights on HVAC. Doorbell. Anything can be transmitted. Digital logic such as switches, potentiometers/voltage levels (analog) have been tested. Other sensors with SDA interfaces can be used. PIR, IR, Hall effect, pressure sensor, gas, smoke, etc. |
