DS18B20+

ELCDS18B20
€3.00 €4.00 -€1.00

The DS18B20+ is a programmable resolution 1-wire digital thermometer in 3 pin TO-92 package. This digital thermometer provides 9bit to 12bit celsius temperature measurements and has an alarm function with non-volatile user programmable upper and lower trigger points. The DS18B20 communicates over a 1-wire bus that by definition requires only one data line (and ground) for communication with central microprocessor. In addition, the device can derive power directly from data line (parasite power) by eliminating need for an external power supply. Each DS18B20 has a unique 64bit serial code stored
