It’s summer and you’re sweating and your hair’s all frizzy and all you really want to know is why the weatherman said this morning that today’s relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%. Enter the HDC1008 Temperature + Humidity Sensor – the best way to prove the weatherman wrong!
This I2C digital humidity sensor is a fairly accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor – SHT15 Breakout It has a typical accuracy of ±4% with an operating range that’s optimized from 10% to 80% RH. Operation outside this range is still possible – just the accuracy might drop a bit. The temperature output has a typical accuracy of ±0.2°C from -20~85°C.
The HDC1008 sensor chip has 2 address-select pins, so you can have up to 4 shared on a single I2C bus. It’s also 3-5V power and logic safe so you don’t need any level shifters or regulators to use with a 5V or 3V microcontroller.
Such a lovely chip, but only available in a tiny BGA package. So we spun up a breakout board with the chip and some extra passive components to make it easy to use. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You’ll need to solder the header onto the PCB but it’s fairly easy and takes only a few minutes even for a beginner.
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.
