Ocado, an online grocery store in England, prides itself on its delivery of refrigerated foods: When the company says the goods will arrive at a certain temperature, they mean it.
The promise is more than a marketing boast. Aided by microchip transmitters, heat sensors and a fast-growing form of wireless communication, the boast is a measurable fact.
Inside each Ocado delivery van is a SIM-card module the size of a postage stamp that monitors the air temperature. The sensor sends data to a computer used by fleet managers back at headquarters near London every few minutes.
Ocado says incidents of spoilage of goods have declined since the transmitters were installed last year.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
