The emitter 'emits' electrons, and they are 'collected' by the collector. The base is used to control this flow of electrons. If a small current flows from the base to the emitter, a much larger current will flow from the collector to the emitter. How much larger this C-E current is...
The digital o/p is permanent and the analog o/p threshold can be changed. The working principle of soil moisture sensor is open & short circuit concept. Here the LED gives an indication when the output is high or low. Soil Moisture Sensor When the condition of the soil is dried up, th...
The working principle of this technique is shown in Fig. 5. A standard 3.5 mm audio jack has four terminals: the left and right audio channels, the common ground and the microphone input. The power is harvested from one of the two audio channels (left channel in Fig. 5) that ...
Let see principle of operation: The Arduino sketch gets a command from serial port and actvite/deactvate output or send value back. The command has to be 7 chars long and begin with *CMD and end with /. Between “*CMD” and “/”, you have to put the pin number (02, 03, 04,...
The ACS712 current sensor is based on the Hall Effect principle, where a magnetic field perpendicular to the current flow generates a voltage proportional to the current passing through the sensor. Hall Effect (source) This voltage can then be converted into a current measurement by reading the ...
Working Principle : When the MOSFET is ON When the MOSFET is ON, current flows through the inductor (L), load (R) and the output capacitor (C ) as shown in fig-2. In this condition, the diode is reverse biased. So no current flows through it. During the ON state magnetic energy ...
Working of Hall Effect Sensor Module This Hall Effect sensor works on the principle of the Hall effect, which states that whenever a magnetic field is applied in a perpendicular direction to the flow of the current, a potential difference is induced. In other words, the Hall Effect is the ...
This sensor works on the principle of laser scattering. The sensor has a fan which creates a controlled airflow so the environmental particulates pass through a focused laser beam. The particulates cause light scattering which is detected by a photodiode and then converted into PM concent...
Hovercraft Working Principle The basis working principle of a hovercraft is that the craft is lifted by a cushion of air. The central propeller blows air into underneath the craft, which inflates a skirt made out of soft material. When the air pressure in the skirt is high enough, the craf...
