Ultrasonic Pest Repeller : (electronic design / schematic added 2/05) |
|
Ultrasonic Pest Repeller: It is well know that pests like rats, mice etc are repelled by ultrasonic frequency in the range
of 30 kHz to 50 kHz. Human beings can’t hear these high-frequency sounds. Unfortunately, all pests do not react at the same ultrasonic frequency. While some pests get repelled at 35 kHz, some
others get repelled at 38 to 40 kHz. Thus to increase the effectiveness, …. (added 10/05) |

Ultrasonic range finder uses few components: 06/24/99 EDN-Design Ideas (added 2/06) An ultrasonic, or sonar, range
finder is a common sensor in robotic systems and industrial environments. Even home and automotive uses are possible. A novel sensor design consists of a WC, a few peripheral components, and a
pair of ultrasonic transducers (Figure 1). The range-finder module consists of a WC, a transmitter, a receiver, a direct-receive inhibit circuit, and an RS-485 interface. The module's usable
range is approximately 4 in. to 16 ft with an accuracy of approximately ±2 in. This performance is sufficient for many industrial, automotive, and robotic uses.... |

|
Ultrasonic Switch: Circuit of a new type of remote control switch is described here. This circuit functions with inaudible
(ultrasonic) sound. Sound of frequency up to 20 kHz is audible to human beings. The sound of frequency above 20 kHz is called ultrasonic sound. The circuit described generates (transmits)
ultrasonic sound of frequency between 40 and 50 kHz. As with…. (added 10/05) |
