The DS18B20 is a digital temperature sensor from DALLAS USA. It can be used to quantify the environmental temperature testing.
The sensor reads temperature range -55 ~ +125 ℃, with inherent temperature resolution of 0.5 ℃ and 9-12 bit serial output
Multi-point networking mesh temperature mea..
EcoDuino is evolving. The EcoDuino now has an enclosure so it is protected from water splashes and safe to use beside your plants. The Ecoduino has an Atmega32U4 which eliminates the requirement for an adapter. Sketches can simply be uploaded via Micro USB just like the Arduino Leona..
Why measure EC? The salinity of the soil, irrigation water or fertilizer solution is an important parameter affecting the root zone environment of your plants. Any of these factors can have a significant effect on plant growth and quality. The presence of high salt levels is your warning sign to mak..

The DS1307 Real Time Clock developed by one of the DFRobot designers: Waiman. The module comes fully assembled and pre-programmed with the MST current time. The included Lithium coin cell battery (CR1225 41mAh) will run the module for a minimum of 9 years (17 years typical) without external 5V..
This 2m long One Wire Temperature Sensor has a waterproof probe and long wire shape, suitable for immersive temperature detection. The chip inside this sensor is the widely adopted DS18B20.
The original wire had three wires inside and you needed to add an extra resistance to get it working. We adju..
This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal de..
This waterproof temperature sensor kit is uses the DS18B20 probe with a resister module making it easy to connect to an Arduino.
The DS18B20 temperature sensor provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected ..
