This is a perfect project for new mums and dads or anyone that needs to be alerted without making a sound. Included is a simple base station that picks up wireless signals, a sensor (in this case a sound level sensor) and a strobe light. As soon as the baby cries the strobe light will go off alerting you. Whilst 1 detector is included in this project you can use any number of different types, depending on what you want to measure and be alerted for (temperature, moisture, door entry, ph levels, etc.).
