Current cost sensors are
0) Main electricity sensor – clamp on incoming live cable
1) Gas pulse sensor – see entry below
2) light sensor – photo resistor (about 2M ohms dark to 100 ohms bright light) as sensor across the channel inputs on the Current Cost dev board.
Current Cost sensors are read by Arduino, displayed on 4×20 lcd module and uploaded to Pachube via Adafruit XPort shield every 15 minutes.
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.
