Celsius to digital thermometer Works with remote sensor: 04/15/04 EDN Design Ideas / (added 1/05) You can
use a single-supply system to precisely measure the temperature at a remote location with less than 1°C error over a 0 to 100°C range (Figure 1). The circuit includes T1, a low-cost AD590
temperature sensor; IC1, an AD8541 rail-to-rail amplifier; four resistors; a trimming potentiometer; and an ADC.... |

Quartz crystal based remote thermometer features direct Celsius readout: 03/17/05 EDN Design Ideas / (added 5/05)
Although quartz crystals have served as temperature sensors, designers haven't taken advantage of the technology because few manufacturers offer the sensors as standard products (references 1
and 2). In contrast to conventional resistance- or semiconductor-based sensors, a quartz-based sensor provides inherently digital-signal conditioning, good stability, and a direct digital

Thermocouple Interfaces to Serial Port: 11/09/95 EDN-Design Ideas / (added 3/03) The circuit in Figure 1 acquires
temperature data via an IBM PC serial port using a thermocouple-based sensor. The sensor is a type-K (chromel-alumel) thermocouple. When in contact, the dissimilar metals produce a potential
difference that is a function of temperature. Additional thermocouple junctions form where the chromel and alumel make contact with the copper connections of the signal-conditioning circuitry.
Thermocouple measurements are inherently differential. Placing the incidental (chromel- and alumel-copper) thermocouple junctions in an ice bath traditionally maintains the reference
junction..... |

Transistor Forms RS-232C Digital Thermometer:
05/09/96 EDN-Design Ideas / (added 6/06) An ordinary transistor can serve as an uncalibrated temperature sensor (Figure 1) for an accurate, PC-compatible thermometer. Unadjusted accuracy is
more than 0.5°:C over the -50 to +50°C range, and the only limitation on resolution is the time devoted to measurement acquisition. For example, 0.1°:C resolution requires less than 1 sec. The
thermometer derives all its power from the RS-232C COM port. Therefore, a laptop computer running a simple data-logging program yields an inexpensive, portable temperature-logging system....
