Microcontroller interface electrometer
A method for measuring static electricity for a science project was sought. An old copy of "Getting Started in Electronics" by Forrest M. Mims III was referenced for guidance.
To create a static electricity measurement circuit, a simple design can be...
Pump Controller For Solar Hot Water System
This circuit optimizes the operation of a solar hot water system. When the water in the solar collector is hotter than the storage tank, the pump runs. The circuit comprises two LM335Z temperature sensors, a comparator, and a MOSFET. Sensor...
Temperature Sensor
The LM35 temperature sensor provides an output of 10 mV/°C for every degree Celsius over 0°C. At 20°C, the output voltage is 20 x 10 = 200 mV. The circuit consumes 60 µA. The load resistance should not be less...
repair microcontroller circuit
The difference between these two ICs. A microcontroller is a specialized type of microprocessor designed to be self-sufficient and cost-effective, while a microprocessor is typically intended for general-purpose use, such as in personal computers (PCs). The microcontroller integrates several useful...
SOT Temperature Sensors with Period/Frequency Output
This is a low-current temperature sensor with a single-wire output. The number of pins required to interface with a microprocessor is minimized by this design.
The low-current temperature sensor operates efficiently by utilizing a single-wire communication protocol, which significantly reduces the...
Coffee Thermometer Circuit
The circuit presented is designed to prevent burning one's tongue by monitoring the temperature of coffee. It consists of a voltage regulator, a temperature-to-voltage converter, a comparator, and two LEDs. In general, the circuit operates as follows: if the coffee...
temp sensor circuit and code
The schematic diagram illustrates the temperature sensor that is set to be launched. The LM135 sensor, functioning as a Zener diode, is connected via a foot-long cord to the circuit through a plug. This design allows the sensor to be...
High-Accuracy Thermometer
This circuit integrates a current source and a platinum RTD bridge to create a high-accuracy thermometer. The ground-referred RTD is part of a bridge that includes the current drive and the LT1009 biased resistor string. The current drive enables the...
Automatic Fan Control circuit
Automatic fan control circuit. This circuit turns a 12V DC fan or CPU fan on or off based on temperature readings. The temperature can be adjusted using VR1.
The automatic fan control circuit operates by monitoring the temperature of its...
