DS18b20 Temperature Sensor: In-Depth. The DS18B20 is a digital thermometer that can provide 9-bit to 12-bit resolution and can measure temperatures from -55°C to +125°C. This is a unique chip designed ...

I built a solar water heater controller 25 (?) years ago and being cheap and lazy I used diodes for temp sensors to make a differential thermostat. The sensitivity is low, so I just used 5 in series.

ARDUINO_LCD.print(temp_c); //display the temperature in celsius on LCD screen ARDUINO_LCD.setCursor(0,1); // Sets the location at which subsequent text written to the LCD will be displayed (at ...

In order for the fish tank and hydroponic garden (located in AM103) to be sustained, there are many working parts that must be maintained, including the utilization of a temperature sensor. The ...

Emergence of Controlled Environment Agriculture (CEA) ranging from computer controlled water irrigation system to lightning and ventilation has changed the conventional scenario of farming. This paper ...

A water temperature sensor was integrated into the Arduino Nano and uses a KY-013 bead (module). This my be easily replaced/re-coded for use with a DS18B20 sensor. For the water temperature sensor, ...

BMP280 Pressure Sensor with Arduino UNO – Connection Diagram. Now that we completely understand how the BMP280 Sensor works we can connect all the required wires to the Arduino UNO board, and in this ...

For additional water quality information, the device also has an Arduino Nano connected to pH, TDS (total dissolved solids), and water temperature sensors which then are fed to the Pi via a serial ...
