Introduction
To avoid misplacing your expensive device, or to track your precious pets, we are here with another great circuit for you. The tracking transmitter circuit. So, in this tutorial, we are going to discuss the “Tracking transmitter circuit diagram”. This tracking transmitter circuit may be used to locate and track mobile items or animals. This can be connected to any moving object, and we can follow it with the help of an FM radio. The circuit uses very few easily available electronic components including BC547, inductors, and capacitors.

Tracking Transmitter Circuit
Working Explanation
This Tracking transmitter circuit diagram is made to send high-frequency short bursts of data. This circuit is powered by a 3V battery, and we can acquire variable RF frequency by using the c7 capacitor as a variable capacitor. The capacitor C7 determines the operating frequency, which oscillates the RF signal at 90MHz. The Q1 transistor generates a low-frequency pulse, whereas the Q3 transistor along with the tank circuit generates a 90MHz RF signal. One can enhance the length of the antenna wire to increase the transmission range.
Application and Uses
- The circuit is used in tracking devices.
- Also, it can be utilized in spying.
- In remote-controlled air crafts.
- Because this tracking circuit uses little power and is small, it may be used to monitor objects or animals.
