Get started with Grove sensors with the GrovePi-Zero

grovepi-zero

US-based Dexter Industries has just launched a new Kickstarter which aims to get you started using Grove sensors. The GrovePi-Zero is, unsurprisingly, a Zero form-factor add-on board which gives you plug-in connections for six Grove modules – 3 analog, 1 serial and 2 digital. It comes with software and tutorials (both video and written) to help you. You can get the board by itself for $17 at the moment (early-bird) plus postage and there are other pledge levels which include various sensor modules. Take a look here.

Create a two-person nuclear activation device with Raspberry Pi

Dylan Schuster over at losant.com has taken two Raspberry Pi 3s and hooked them up to two custom turn-key-and-button boxes. He’s then used Losant’s new MQTT and REST clients to make them Internet of Things devices. By sending messages from the two Pis and receiving messages back, the system will only ‘activate’ if both keys are turned. Read more here.

New Enviro pHAT for the Raspberry Pi launched by Pimoroni

Teased in a video stream some weeks ago, the Enviro pHAT has now been launched by Pimoroni. It includes the following:

  • BMP280 temperature/pressure sensor
  • TCS3472 light and RGB colour sensor
  • Two LEDs for illumination
  • LSM303D accelerometer/magnetometer sensor
  • ADS1015 4-channel analog to digital converter (ADC)

As well as the included sensors, the ADC provides 4 channels for you to plug in your own sensors.

As usual, the pHAT comes with a Python library allowing you to get readings and display them.

You can get hold of the Enviro pHAT for £16 (plus shipping) from Pimoroni.
