Wiring reference for solar lipo charger (with battery backup) powering Adafruit Trinket and FONA which posts battery voltage and other parameters to a ThingSpeak website located here: https://thingspeak.com/channels/62784

The installed unit posts battery voltage, analog response for rain presence, and analog repsonse for soil moisture (on/off) from a remote location on the San Pedro River watershed in Arizona to a ThingSpeak website using a FONA breakout (cellular service). The circuit is powered from lipo battery and solar power for charging. Voltage is analogous to what most sensors report to a microcontroller pin, so code for battery voltage reporting can be replaced accordingly. The design shared on this site is for temperature and humidity data collection.

Meant fritzing, not frizzing. Wish I could edit these comments.

Still working. Updated site with new frizzing files showing circuit working with a DHT sensor.

Field installation going strong after three months of summer heat and monsoon rains. Measurement frequency: 10 minutes; 12,890 records collected; Average Collection Interval: 12.45 minutes; Standard Deviation: 4.28 minutes; Collection interval > 30 minutes: 156 events; Max collection interval: 59 minutes; Installation: $350 + $11 / month.

Migrating this to a strip board; not yet tested, but included in downloads.

so can you send me the coding for the arduino and fritzing work for this project. how many days can you work on this?

Very cool! I am going to have to put one of these together for my mom. Do you have project details posted somehwere? In regards to your comment - yes, you are correct - I should develop a video that explains the purpose and intent a little more clearly.

hello can you do something like this Name of project: The Development Of An Arduino Based Guidance System For The Elderly Example: youtube link: https://www.youtube.com/watch?v=ZYRAWr7sADM
