Very cool project from Victorien, Clément Martin on Hackster.io:
For several years, beekeepers have noticed a high mortality of their hives. The bees leave hives abruptly without warning signs. That’s why we’ve created a system that controls temperature and humidity inside a hive, to detect any health problem.
This system is connected and the data collected can be consulted online. The system makes a measurement every 40 minutes. Moreover, it’s possible to see the battery power level to know when to recharge the system.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
