Measure the ambient temperature around the chip. The output voltage of the temperature sensor is proportional to the temperature. The obtained temperature is measured by ADC. Inside the chip, the temperature

Lm35 is a precision temperature sensing IC series released by US National Semiconductor (later acquired by TI). Its signal output mode is analog output, and the output voltage value is proportional to the Celsius temperature value, the user can obtain high measurement accuracy without any extra correction. Its main features include: Power supply voltage: 4 ~ 30 V Measurement Range: Related to the chip. T

devices can be hung on the bus, with different device addresses to access different devices. Similarly, the 1-wire bus can hang multiple devices, but it has only one line, how to differentiate between different devices. There is a unique 64-bit long serial number inside each DS18B20, and this serial number value exists in the DS18B20 internal ROM. The first 8 bits are the product Type code (DS18B20 is 0x10), and the next 48 bits are the unique serial number for each device, and the last 8 bits

SI7021 is a temperature and humidity sensor chip produced by Silicon Labs. Its main features: Humidity accuracy: Error typ. +/-2%RH, Max +/-3%rh (0~80%RH), factory corrected Temperature accuracy: Error typ. +/-0.3%°c, Max +/-0.4%°c ( -10°c~85°c), factory corrected Measuring range: Temperature range 0~1
