Ultrasonic sensor HC-SR04 is used to measure distance in range of 2cm-400cm with accuracy of 3mm. The sensor module consists of ultrasonic transmitter, receiver and the control circuit. The ultrasonic ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

Utilizes the Blynk IoT platform to display water level data remotely. Allows users to monitor the water level via the Blynk mobile app or dashboard. Ideal for users who want remote access and ...

The non-contact liquid level sensor uses the sensing capacitance of water to detect the presence of liquid approaching the sensor. The sensor has a specific static capacitance due to the distributed ...

The CLD series features a unique pulsed ultrasonic technology to enable a very high degree of accuracy and reliability. This non-invasive design, with no contact between the sensor and the fluid, ...

The Arduino Uno is powered by the ATmega328P, an 8-bit microcontroller that runs at 16 MHz. It has 32 KB of flash memory, 2 KB of SRAM, and 1 KB of EEPROM. The board has 14 digital I/O pins (of which ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil was left in ...
