Product Description
3pin Temperature Sensor DS18B20 Programmable Resolution 1-Wire Digital Thermometer GXCAS18B20 9-12bits TO-92
GX1820 is perfectly compatible with DS18B20, which is more accurate and shipments exceed 10 million. Many Chinese grain A -level suppliers use this chip as food, tobacco, port, water temperature and other fields.
The DS18B20 Digital Thermometer provides 9 to 12–bit centigrade temperature measurements and has an alarm function with nonvolatile 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 a central microprocessor. It has an operating temperature range of –55°C to +125°C and is accurate to +/-0.5C over the range of –10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1–wire bus; thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, and process monitoring and control systems.
PIN DESCRIPTION GND - Ground DQ - Data In/Out VDD - Power Supply Voltage NC - No Connect
It is always used for temperature sensor assembly, welded to silicone cable then encapsulated in stainless steel tube .
- Unique 1-Wire interface requires only one port pin for communication
- Each device has a unique 64-bit serial code stored in an onboard ROM
- Multidrop capability simplifies distributed temperature sensing applications
- Requires no external components
- Can be powered from data line. Power supply range is 3.0V to 5.5V
-Measures temperatures from –55°C to +125°C (–67°F to +257°F)
- +/-0.5C accuracy from –10°C to +85°C
- Thermometer resolution is user-selectable from 9 to 12 bits
- Converts temperature to 12-bit digital word in 750ms (max.)
- User-definable nonvolatile (NV) alarm settings
- Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
- Available in 8-pin SO (150mil), 8-pin SOP, and 3-pin TO-92 packages
- Software compatible with the DS1822
- Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
