Velleman IR Beam Break Detector Solder kit
• Create an alarm that triggers when someone enters a room or when there is movement in a certain area
• Two units create a IR beam and activate when the beam is broken
• A great introduction to soldering, with 20 parts
• Requires two 9V batteries (not included, Order Code L46AL)What can I create with this kit?
Use this beam break kit (manufacturers code MK120) to build a handy little alarm with a sensor that triggers a speaker and LED warning. This kit is a great way to demonstrate the IR beams used in some burglar alarms, door chimes and smoke alarms. You can combine the sensors with other kits to trigger a response. When something moves between the transmitter and receiver, the beam is broken and the alarm is triggered. You could use this to prompt a camera to take a photo or make a light switch on. With 40 parts and two boards, this is a fun and rewarding kit for everyone.
What can I learn from this IR beam kit?
You can practise soldering and learn about electronics and circuits with this IR beam kit. It uses resistors, capacitors, transistors, LEDs and speaker – and you can learn how they are connected in a circuit. IR projects a beam between units and offers a good example of basic wireless technology. This is a great kit to expand and experiment with. This kit requires a soldering iron and solder and may require wire cutters.
How easy is this kit to solder?
Simple to solder, this kit is ideal for beginners learning about electronics or for those looking for a trigger to add to other projects. Putting the kit together is just the start of your adventure. You could use external material to create an enclosure for the kit to protect the electronics or make it blend into the environment. This kit comes with a holder for a 9V (PP3) battery (not included), which is needed for the receiver and transmitter. A DC jack is required to attach a power supply. This kit is not recommended for outdoor use.
