Product Description

FST Series DS18B20 Programmable Resolution 1 Wire Digital Temperature Sensor

DS18B20 is 1-Wire interface Temperature sensor manufactured by Dallas Semiconductor Corp. The unique 1-Wire Interface requires only one digital pin for two way communication with a microcontroller.

Flexible customize the product specifications and shape to match your applications.

1. How can I get samples?
Discuss to one of our sales, tell him or her your requirements. After confirmed details, we will arrange samples production. Customer need to pay for shipping cost. (Check with sales whether your samples can be free)

2. When can I receive samples?
Normally it takes 15-30 days to produce samples.
