Having deployed my Adafruit Feather version of a Temperature / Humidity LoRa Sensor to make use of my The Things Network gateway it’s now time to build another sensor, this time with a Raspberry Pi Zero.
I have a Pi Supply LoRa node pHAT that adds the radio side of things, but I needed a sensor. The pHAT has a header on the right hand edge which pulls out the 3.3v, 2, 3, 4 and Gnd, pins from the pi.
These just happen to line up with the I2C bus. They are also broken out in the same order as used by the Pimoroni Breakout Garden series of I2C sensors which is really useful.
The Pimoroni Breakout Garden offer a huge range of sensors and output devices in either I2C or SPI. In this case I grabbed the BME680 which offers temperature, pressure, humidity and air quality in a single package.
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.
