MAXIM INTEGRATED / ANALOG DEVICES DS1822PAR Digital Thermometer Module
The DS1822 plus PAR is an economical 1-wire digital thermometer housed in a 3-pin TO-92 package. It provides temperature measurements with a resolution of 9 to 12 bits in Celsius and features an alarm function with user-programmable upper and lower temperature thresholds. The device communicates over a 1-wire bus, requiring only a single data line and ground for connection to a microcontroller. It operates over a temperature range of -55°C to +125°C and maintains an accuracy of ±2°C within the -10°C to 85°C range. The DS1822 can derive power directly from the data line, eliminating the need for an external power supply. Each sensor has a unique 64-bit serial code, allowing multiple devices to operate on the same bus for large-scale temperature monitoring and control. Applications include HVAC systems, environmental controls, temperature monitoring, and process control.
