CamJam EduKit 3 - Further adventures
Cat Lamin previously reviewed her initial use of CamJam EduKit 3 with her friend Louise. Well, now the ladies have had another hack session and progressed to using the sensors included in the kit. She recounts their escapades here.

This is a great resource suitable for home use and for event workshops.
DHT temperature sensor
The DHT11 temperature and humidity sensor is an inexpensive sensor. It has a +/- 2 degree variance, so it’s not suitable for high-precision use-cases (for that you need the DHT22). Over at Circuit Basics, they’ve written a tutorialwhich will get you started with the sensor. They’ve included code for both C and Python (using an Adafruit library) and also highlighted how to display it to a small LCD screen (as pictured). Read how to do it here.
