![]() ![]() ![]() 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. 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. 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. Safety is another reason to choose solar lights. You’ll also be grateful when your power bill comes since these lights aren’t using electricity. You can see sun positions at sunrise, specified. They don’t require any wiring or other power sources, making it easy to place them in the ground. SunCalc is a little app that shows sun movement and sunlight phases during the given day at the given location. Arduinos have limited memory, so taking a photo may be difficult. Simple installation is the best reason to choose them. 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. The garden sunlight meter you linked to only gives a measurement of the amount of sunlight at the point in time you happen to be looking at it. So if planning to use battery, you need to ditch the "development aids" to conserve power. Once deployed, you do not need this extra stuff, but they still consume power - even if you "put the arduino into low power modes". And while you’ve probably got a favorite weather app and might enjoy Augmented Reality constellation hunting with your kids via Night Sky, chances are you haven’t heard of this app quite yet. Why? Because your standard arduino had extra stuff to make it easy to use. Point being, whether you’re an astronomer, gardener, or photographer there’s often a need to scout the sun’s path across the sky. The thin yellow-colored curve shows the trajectory of the sun, the yellow deposit shows the variation of the path of the sun throughout the year. You can change the suns positions for sunrise, selected time and sunset see. Most other sites dont take the terrain into account. ![]() If using a power supply orPoE, it won't matter as much. SunCalc shows the movement of the sun and sunlight-phase for a certain day at a certain place. What is Suncurves Weve developed a method to compute accurate sunrise and sunset times for every day of the year. Ultimately you will need to look at standalone arduino for deployment and sleep (low power modes) if you plan to run on batteries. Consider the optimal locations for both hardscaping and softscaping elements by studying sun and wind patterns around your yard. ![]()
