Your thermal comfort is roughly half from air convection and half from the Mean Radiant Temperature (the average temperature radiating from all surfaces in a room). Existing radiant heating and cooling systems don’t measure the mean radiant temperature—they just measure air temperature, or the temperature of one or two surfaces in the room.
Reading both air temperature and the mean radiant temperature gives the more accurate “operative temperature”, so controls can keep people more comfortable and use less energy at the same time….
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
