The project presented here is a Wireless Humidity and Temperature Transmitter that utilizes a DHT22 sensor to measure temperature and humidity levels. The data is then transmitted via an NRF24L01 RF transceiver module to a receiver board, which displays the readings on an OLED...

This Wireless Analog Sensor project is a cost-effective solution for transmitting live data and enabling continuous monitoring, logging, and plotting sensor measurements. The system utilizes a 434MHz RF module and an Arduino-compatible microcontroller, ATMEGA328, to transmit data from...

This single-supply, low-side, current-sensing solution accurately detects load current between 10μΑ and 10mA. A unique yet simple gain-switching network was implemented to measure the three-decade load current range accurately. The linear range of the output is from 100mV to 4.90V....

This project is based on IVC102 chip from Texas Instruments. This chip is a precision integrating amplifier with FET OPAMP, integrating capacitors, and low leakage FET switches. It integrates low-level input current for a user-determined period, storing the resulting voltage on the...

This is a simple signal conditioner circuit for Piezoelectric sensors. The circuit converts the input charge to voltage and the level shifts to the ADC input range of 0.1 V to 2.4 V. The circuit is built using AD8608 OPAMP from Analog devices. Piezoelectric elements are used to...

The project presented here is an analog capacitive humidity sensor converter board suitable for various humidity measurement tasks. The circuit comes from Texas Instruments application note (see below). Most conventional capacitive proximity sensors produce a digital signal, but this...

The project presented here is an analog capacitive proximity sensor. The circuit is from Texas Instruments application note. Most conventional capacitive proximity sensors produce a "1" or "0" output, this circuit produces a DC output that is a function of the size and relative...

This project allows users to monitor the liquid level on a Bar-Graph display. The liquid level is measured using a pressure sensor, the sensor is placed on top of the tank and is connected to an open-ended tube that is submerged in the water tank. The amount of water in the tank...
