One wire digital temperature

The DHT22 (RHT03) is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old. Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground. Although it uses a single-wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin! Features: Low cost 3 to 5V power and I/O 1-1.5mA measuring current uA standby current 2.5mA max current use during conversion (while requesting data) Good for % humidity readings with 2-5% accuracy Good for -40 to 80°C temperature readings ±0.5°C accuracy No more than 0.5 Hz sampling rate (once every 2 seconds) Body size 27mm x 59mm x 13.5mm (1.05″ x 2.32″ x pins, 0.1″ spacing   Feature & Application: High precision Capacitive type Full range temperature compensated Relative humidity and temperature measurement Calibrated digital signal Outstanding long-term stability Extra components not needed Long transmission distance, up to 100 meters Low power consumption 4 pins packaged and fully interchangeable Shipment Details We ship the item from our side on the same day or on the next working day after receiving payment.

DS18B20 Programmable Resolution 1-Wire Digital Thermometer DS18B20 Programmable Resolution 1-Wire Digital Thermometer The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius 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 ±0.5°C 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. Key Features Unique 1-Wire Interface Requires Only One Port Pin for Communication Each Device has a Unique 64-Bit Serial Code Stored
