Product description: Gravity - kit with DS18B20 temperature sensor - DFRobot KIT0021
A set consisting of a waterproof probe with a DS18B20 sensor , an adapter for digital and analog sensors with clamp connectors and a Gravity connecting cable . The sensor was placed in a very tight casing, thanks to which it allows temperature measurement in extremely humid conditions. In addition, the probe cable is about 90 cm long , which allows you to measure the temperature in a place that is not directly next to the connected microcontroller. Using the DS18B20 probe, we can measure the temperature in the range from -55 ° C to 125 ° C , with an accuracy of ± 0.5 ° C. The cable has been covered with a PVC layer, therefore the manufacturer suggests not to subject it to temperatures higher than 100 ° C. The kit is widely used in many areas such as soil temperature measurement, hot water tank temperature control, etc. It supports multi-point measurement.
