LB-27: Micropower Thermometer - National Semiconductor Application Note (app
note added 2/06) |
|
LCD thermometer - Build your own temperature meter for fun. This project uses the
Microchip TC77 digital temperature sensor, a PIC16F871 microcontroller and a 7-segment
3˝ digit LCD. You can study the source code on how to drive an LCD display…..(design

Quartz crystal based remote thermometer features direct Celsius readout - 03/17/05
EDN-Design Ideas: (design idea 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 resistanceor semiconductor-based sensors,... |

Thermocouple Interfaces to Serial Port - 11/09/95 EDN-Design Ideas: 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.....(design idea added 3/03) |

Thermoelectric Controller Scriptable Thermometer - A unified thermometric
controller that can be programmed with simple scripts, integrating the "classic"
thermometer/controller pair. You can build a variety of simple machines with the same
hardware and a different script : a charting thermometer, a vending machine that dials
your number when empty, a leavening cell.... (added 6/06) |

Thermostat With Adjustable Hysteresis - This small thermostat allows you to select
the size of its hysteresis. You can set both the temperature at which the relay will
energize, and the temperature at which the relay will de-energize. The difference
between these two temperatures is the hysteresis. |

Thermostat with LED Temperature Display - I needed to replace two old, unreliable
thermostats for controlling the heating and cooling for a large garden shed.
Commercial basic thermostats are available quite cheaply, but some lack the ability to
control heavy loads or have the extra features that I require for saving energy when
the door is often left open or to indicate temperature being out of range etc. I like
the PIC18F1320 microcontroller used in my previous project, so decided to use it again
in a very similar design to drive three multiplexed LED displays and read the
temperature from a Dallas/Maxim DS18x20 "1-Wire" sensor. ….(design added 11/08) |

Transistor Forms RS232C Digital Thermometer - 05/09/96 EDN-Design Ideas: An
ordinary transistor can serve as an uncalibrated temperature sensor (Figure 1)for an
accurate, PC-compatible thermometer. Unadjusted accuracy is more than0.5°: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.....(design idea added
