And it will produce a LOW output when there is no object detected. Thus, the output LED will turn on when an objected is detected and will be OFF when no object is detected. The 4081 is an AND gate chip. The pinout of the 4081 is shown below, so that you can see how to connect it in the circuit.
UltraLow Power Short Range Radio Transceivers 3 Key Factors The power supply requirement of the transceiver is a key factor in the wireless sensor design and application. Since most ULP sensors run from tiny batte ries and energy harvesting sources, sub 2V supply voltages are highly desired.
This circuit performs an LED PWM dimmer with minimum components and high power efficiency, especially in low LED brightness. It can be powered in a wide voltage range from 4 up to 15 volts. Along with its compact size, it is ideal for camping or night fishing, and generally whenever mobility and longtime use is required.
A pulsing current is applied to the coil, which then induces a magnetic field shown in blue. When the magnetic field of the coil moves across metal, such as the coin in this illustration, the field induces electric currents (called eddy currents) in the coin.

The circuit designed using transistor T1 (BF494) as a basic lowpower variable frequency VHF oscillator. A varicap diode circuit is included to change the frequency of the transmitter and to provide frequency modulation by audio signals. The output of the oscillator is about 50 milliwatts. Transistor T2 (2N3866) forms a VHFclass A power amplifier.
