HS Code 9025900090 Production Capacity 500, 000PCS/Year Product Description Product Description The DS18B20 digital temperature sensor provides 9-bit to 12-bit celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points...
Another advantage is that each DS18B20 sensor has a unique 64-bit serial code, which allows multiple sensors to function on the same 1-Wire bus. So you can read data from multiple sensors that are connected together with just one Arduino pin (see code examples below). The resolution of the...
1.电路的电流一般很小,只有当DS18x20进行温度转化或者写EEPROM时会高达1.5mA,当DS18x20进行上述操作时,数据线必须保持电平拉高状态直到操作结束,期间master端的Arduino不能做任何操作,DS18x20温度转化时这个时间间隔大概是750ms。 2.如果要求DS18x20有精确的转化,数据线在温度转化期间必须保证足够的能量,但当你使用多...
DS18B20 is a digitaltemperature sensorwhich is from DALLAS U.S. It can be used to quantify the environmental temperature testing. The temperature range -55 ~ 125 ℃, the inherent temperature resolution of 0.5 ℃, support multi-point networking mesh. Three DS18B20 can deloyed on three lines, ...
In this tutorial we will show how to build DS18B20 and ESP8266 temperature sensor without Arduino. We will use Arduino IDE and report temperature over WiFi on EasyIoT server. Sensor temperature is visible in EasyIoT server Web interface. If data logging is enabled you can see temperature chart...
*连接一个DS18B20温度传感器到Arduino *用单线接口从传感器读取数据 *直接通过Arduino发送数据至xively.com *在网络上查看到 结果图 http://xively.com是一个物联网主机,可以基于你提供的数据来生成图片。 在这个例子中我会去监控我房间里的温度。 第一步:材料清单 ...
