Solar-powered Raspberry Pi Pico plant watering monitor project
HTML-код
- Опубликовано: 23 июл 2024
- I've finally achieved my ambition to make a compact, self-sustaining, solar-powered soil moisture monitor using a Raspberry Pi Pico, and here is the full build video - including electronics, construction and coding. All done on a tight budget, I've used inexpensive solar panels from Pimoroni and an Adafruit multi-input charger for my Lipo battery, as well as a Raspberry Pi Pico W, all encased in a small plastic box. Micropython code with the deepsleep can be found here: github.com/PaterPracticus/Pla...
NOTE - since posting this video the monitor has been running continuously on solar power alone, but I've noticed that my timings drift very slightly each wake cycle while the Pico boots up and launches the programme. I've now calculated this at 0.814 seconds and taken that off the time in deepsleep. Наука
Since posting this video, the monitor has been running continually on solar power alone, but I've noticed that my timings drift very slightly each wake cycle while the Pico boots up and launches the programme. I've now calculated this at 0.814 seconds per cycle and taken that off the time in deepsleep.
very nice
Thanks. Glad you liked it.
Would you mind listing the components used? - I'm especially interested in the solar panel and charger
Of course. The Raspberry Pi is a Pico W, panels are Pimoroni 3.0V 100mA Polycrystalline Solar Cells and the charger an Adafruit Universal USB / DC / Solar Lithium Ion/Polymer charger - bq24074. I got the panels and the charger from the Pimoroni online shop. PP
good morning sir
We are some students from standard 12th in India
We need some assistance as we are making a Smart City Project and are participants for a national TechFest
We need some assistance from you and will be greatly indebted to you sir
Thank you sir
