Do you need to operate OpenSprinkler where there is no power and ethernet?
With OpenSprikler Solar you can!I started with the idea to Port the version of Opensprikler 2.16 working on Esp8266 to OS Bee 2.0.
I needed a HW prototype based on Esp8266 and capable to drive Self Latching Valve’s and using a Oled 128×64 LCd
Building this unit, since all the components have a reduced power drain, I came across with the idea of building a fully autonomous device.
I experimented with different batteries capacity and solar panel powers:
At the end a 3.7v Lipo with 5000mAh and
A Solar panel of 5w
where my best choice in term of cost and dimensions.Since I am a noob in electronics, I have chosen to build this unit using breakout boards easily available over the web with a total cost of about 30$.
Detail of the DIY project can be found at GitHub.com/pbecchi/OpenSprinkler-Solar.git.I have uploaded in https://github.com/pbecchi/OpenESP8266_Sprinkler/tree/ForOS_Bee2_0%2COS_Solar%2COS_3_0/OpenSprinkler_Arduino_V_2_1_6
A new release of Open Esp8266 Sprinkler! This new release contain several improvements and also run on OS Bee 2.0 ,on OpenSprinkler 3.0 and in OpenSprinkler Solar.
Changes from previous releases are identified and described in https://github.com/pbecchi/OpenESP8266_Sprinkler/blob/ForOS_Bee2_0%2COS_Solar%2COS_3_0/OpenSprinkler_Arduino_V_2_1_6/OpenSprinkler%20SW%20new%20features.md.
