Wireless Coupler Terminal Interface
The purpose of the terminal interface is to allow my computer to communicate with Minimum Mass Wireless Coupler equipped devices using a terminal emulator program. Consequently, the Base Unit is basically an RS-232 interface and Minimum Mass Wireless Coupler. The...
Scoobas Solution Sensing Tactic
This document serves multiple purposes, primarily to document the methods employed by a Scooba robot to detect: a) the presence of an acceptable cleaning solution being delivered to its pump, and b) the excess presence of used solution collected off...
WIRELESS MICROPHONE
An operational amplifier integrated circuit (741) amplifies the audio signal from microphone 1 (MIC1), with resistor R12 determining its gain. The amplified audio signal is then directed to the oscillator circuit, which includes transistor Q1 and associated components. D2 functions...
6m wireless remote control switch circuit
This example describes a wireless remote control switch featuring reliable operation and practical characteristics, capable of remotely controlling a 6-channel device within a 6-meter range for household electricity. The wireless remote control switch circuit consists of a wireless transmitter and...
Automatic plant waterer
The unit consists of a sensor, timer, and electric water pump. The sensor is embedded in the soil, and when dry, the electronics operate the water pump for a preset time. The circuit is composed of a level-sensitive Schmitt trigger,...
Wireless IR Headphones circuit
This wireless infrared (IR) headphones circuit project enables the transmission of audio signals through an infrared connection. The circuit consists of two main components: a transmitter and a receiver. Unlike radio frequency (RF) transmitters, both parts of this application must...
Wireless am microphone
The transistor Q1 and its associated components form a tunable RF oscillator. The RF signal is directed to transistor Q2, which functions as the modulator. Operational amplifier IC1 amplifies the audio signal and transmits it through resistor R4 to the...
Wireless remote control switch circuit 5
The wireless remote control transmitter circuit consists of control buttons S1 to S16, resistors R1 to R3, a capacitor C1, a regulator diode VS, a crystal oscillator BC1, and DTMF encoder integrated circuits IC1 and IC2. The circuit components are...
Schematic of The Infrared Rays Wireless Headphone
The transmitter circuit for inductive headphones must be installed on a wall or ceiling, limiting their use outdoors. This is a significant drawback of inductive headphones. In contrast, infrared wireless headphones do not have this limitation; their flexible infrared transmitter...
