Temperature Sensor uses I2C isolator: 06/06/96 EDN Design
Ideas / (added 5/03) You can couple an LM75 digital output-temperature sensor through an isolated I2C (interintegrated circuit)
interface (see Reference) as shown in Figure 1. Electrically isolating the sensor allows operation in situations prone to high common-mode
voltages; it's also useful in breaking ground loops. IC1 and IC2 comprise a bidirectional isolator. |
|
Temperature Sensor with Digital Output : This is a very simple to
implement Temperature Sensor. It uses LM35DT as a semiconductor temperature sensor which operates with a +5 volt DC. It produces an analog
output voltage, proportional to the change in surrounding temperature in Celsius scale (2mv/C). The analog output of the sensor is then passed
to the ADC0804 IC which produces an 8-bit binary output (digital output) correspoding to the analog input voltage. The digital output from ADC
is then used to glow the LED which indicates the high/low logic (LED ON: Logic 0, LED OFF: Logic 1).... (added 10/05) |

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 (chromeland 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 3/03) 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.... |

Transistors offer thermal protection for Controller:
07/19/01 EDN Design Ideas / (added 10/03) When a switch-mode power-supply controller, such as On Semiconductor's NCP1200, operates at a
high ambient temperature, you should protect the entire power supply against lethal thermal runaway. The NCP1200 operates directly from the
power mains without an auxiliary winding; therefore, the die in the IC dissipates power (Figure 1).. |
