![]() ![]() I'm not sure about power requirements for ESP, but I suspect it will be more Arduino like than Raspberry Pi in terms of power needs. A sun tracker is a device that is placed in your yard and uses the sunlight to track the movement of the sun. In my case I used Raspberry-Pi for camera work, but Raspberry-Pi requires a heck of a lot more power to run than an Arduino - so you would want to look at PoE or remote power supplies for that. You might be better off using an ESP-Cam. This is not impossible, but might not be trivial. You can use one sun map to track the movement of sun and shadow across your garden, or you can make copies of your map and create a new one for every hour. tables and started to read, and as he read along he lost track of time and lost track of the thoughts of death. At best, if you worked out how to connect a camera and trigger a photo, as the camera passes data to your controller, you would need to relay it to a server for storage on the fly. Arduinos have limited memory, so taking a photo may be difficult. It's not hard to do a standalone arduino, there are plenty of tutorials online if I remember, I will add a link when I get home. So if planning to use battery, you need to ditch the "development aids" to conserve power. DIY chart to measure sunlight in your garden If it’s a large garden area, you might want to map sunlight exposure in the different sections of the garden as they come into the sun, or move into shade. There are two main motions of Earth, daily rotation and yearly orbit. A garden journal can help you keep track of when daffodils bloom in spring. Both apps allow you to export data if you want to print or save it. The measurement of the length of the shadow depends on the height of the obstacle and the elevation of the sun, the formula is: length shadow object height/tan ( sun elevation ). MyGarden Notebook is a paid app for iPhones that allows you to enter plants and garden areas you want to keep track of, and also allows you to map out where your plants are in your garden. Once deployed, you do not need this extra stuff, but they still consume power - even if you "put the arduino into low power modes". Keep measuring garden sunlight in each area every hour until sunset. Track the Sun with simple tools and you will reveal the motion of the Earth. shadow The length of the shadow map is normalized (changing with the zoom), and the direction is opposite azimuth. ![]() Why? Because your standard arduino had extra stuff to make it easy to use. If using a power supply orPoE, it won't matter as much. Ultimately you will need to look at standalone arduino for deployment and sleep (low power modes) if you plan to run on batteries. ![]()
