Automatic-fan-speed-controller
The controller circuit is designed to reduce a fan's noise, power consumption, and wear, especially when operating in low, fluctuating ambient temperatures. A temperature sensor is mounted in the fan's airstream, allowing the circuit to adjust the fan speed as...
Temperature-to-frequency converter
Al's positive input is biased by the thermocouple. Al's output drives a basic voltage-to-frequency (V-F) converter, which consists of 74C04 inverters and related components. Each V-F output pulse results in a fixed amount of charge being transferred from a 100...
T-121 temperature sensors form a temperature control circuit diagram
Adjust RP1 and RP2 to set the preset temperature control point. The 555 circuit is configured as a Schmitt inverter circuit that automatically controls a relay device. This forms part of the T-121 temperature control circuit, which includes a temperature...
digital thermometer using lm35
A digital thermometer is utilized for measuring room temperature. This project serves as a foundational exercise for beginners to comprehend the functions of various pins on the PIC16F877A microcontroller. The design incorporates the analog-to-digital conversion (ADC) capabilities of the PIC16F877A...
heatsink temperature monitor circuit
This heatsink temperature monitor circuit uses three LEDs to signal when the temperature exceeds two boundary levels. When the heatsink temperature is below 50-60°C (122-140°F), the green LED lights up. The yellow LED indicates that the temperature is between 60-70°C...
Board System Monitoring for Temperature and Voltage Condition
This is a circuit of a board system monitoring the temperature and voltage conditions. It uses the NE1617A, which is a 2-channel temperature sensor.
The described circuit serves as a monitoring system for both temperature and voltage conditions, utilizing the NE1617A...
TEMPERATURE REPORTING DIGITAL THERMOMETER
The ROMs or PROMs must contain the correct code for converting data from the NE5037, which serves as the address for the ROMs or PROMs, into the appropriate segment driver codes. The displayed temperature can be converted to degrees Fahrenheit...
Leak Detector
High sensitivity, portable temperature comparator. This sensitive circuit is basically a comparator, detecting very slight temperature changes in respect to the ambient temperature. It was primarily intended to detect draughts around doors and windows that cause energy leaks but can...
