Ultrasonic Sensors to Detect Human Presence

· Our sensors work well with Raspberry Pi’s and many other microcontrollers in order to create a fully functional system. Popular choices for detecting human presence are a few sensors from our HRLV-ShortRange-EZ sensor line.. The wide beam makes these sensors ideal for people detection, autonomous navigation and other wide beam applications.

CN1657956A - Human body detection sensor - Google Patents

A human body detection sensor includes two oscillation circuits, a tuning circuit which connects equivalent points of the two oscillation circuits to each other, an antenna electrode which is connected to any one of the oscillation circuits so that a change in circuit state occurs upon approach of a human body, and a wave detector circuit for detecting a shift of oscillation between the two ...

Novel sensor is capable of detecting human presence ...

· Unlike typical pyroelectric human presence sensors that rely on motion detection, the D6T thermal sensor is able to detect the presence of stationary humans by detecting body heat, and can therefore be used to switch off unnecessary lighting, air conditioning, etc automatically when people are not present (regardless of whether they move or not). As the D6T sensors are also able to monitor the ...
