Add these four sensors to the powerful JackBord and you have a great science starter kit to which you can add more sensors to unleash your curiosity on more projects.
This science kit is designed to get you measuring your environment, log and analyse data and  solve problems, for example to measure the quailty of your local stream.
Each sensor is built into JackBord's unique Universal Sensor Interface (USI) which makes connecting the sensors to the JackBord simple.
The USI makes for easy storage (less likely to lose or damage the small sensor),  protects against accidental wiring mistakes (shorting) and connects to activities using the QR code.
