Kit Seeed Grove 30 sensors for Arduino

The 28 sensor kit is a great extension kit for your micro: bit. Using Sensor shield for micro: bit you can connect all the modules included in the pack only by the connectors without the need to solder or wire any part. Now you can just concentrate on programming with your big mirco: bit.

When the piezoelectric ceramic shock will generate an electrical signal,
the analog port of the Arduino controller may perceive weak vibration signals. Can also be done with jobs related to vibration interactions, such as electronic drums.

Level sensor for liquids with float. The liquid level sensor acts as a switch. Liquid level float sensors are used when constant control and regulation of the liquid level (water, oil and other fluids) is required such as extraction pumps. The sensor is equipped with a float with a magnet which, acting by the buoyancy force of the fluid, moves along the tube, shortening or opening the reed switch.

It can be used to detect liquid levels that are too high or too low. Ideal for all those applications where the level of non-corrosive liquids such as water tanks or aquariums needs to be monitored. It is made of stainless steel.
