The temperature controlling system maintains a user programmable room temperature where air conditioners are not provided. For this purpose we need a cooler and a heater. Cooler is used for decreasing temperature and heater is used for increasing temperature. This project also shows the real time temperature in degree centigrade. It can be used in …
California based company, Integrated Device Technology (IDT) has recently announced their new HS300x family of MEMS high-performance relative humidity (RH) and temperature sensors of dimension 3.0 × 2.41 × 0.8 mm DFN-style 6-pin LGA. Currently, there are four devices in this family—the HS3001, HS3002, HS3003, and HS3004. They are all the same from the view of functionality but differ slightly in terms of the accuracy of …

Data loggers are small, battery-powered devices used to sense and store information in different situations. They include a microprocessor, data storage, one or several sensors and they can record information for a very long period. However, some data loggers do not include sensors, but have ports that allow a sensor to be connected. They are …
Anyone who has ever boiled milk on the stove knows, that it has a nasty habit of overflowing. That is why I created the temperature alarm for boiling milk to be used my mother. It continuously measures the temperature of the milk and sounds an alarm when the temperature is over the preset alarm value. …
Thermistors (thermal resistors) are temperature dependent variable resistors. There are two types of thermistors, Positive Temperature Coefficient (PTC) and Negative Temperature Coefficient (NTC). When the temperature increases, PTC thermistor resistance will increase and NTC thermistor resistance will decrease. They exhibit the opposite response when the temperature decreases. Both types of thermistors are used in a …
This project describes a DIY wireless temperature and humidity monitor for kids’ or infant’s room using the Arduino platform, and inexpensive and easily available ASK transmitter/receiver modules. On the transmitting end, an Arduino nano senses the ambient room temperature and humidity using the DHT22 sensor and transmits the data to a receiving end Arduino over …

Summary One of the most commonly used medical instruments nowadays is the thermometer. The thermometer is used to monitor or measure the body temperature of a sick person. The idea of creating a thermometer started from a device called thermoscope, a thermometer without a scale. Several inventors developed it until Sir Thomas Allbutt invented the …
Maxim’s Collection of temperature sensor and thermostat ICs These temperature sensors offer good accuracy (±1.5°C) over the range of -25°C to +125°C and feature a 2-wire digital output with bus lockup protection and external reset. This is a 5-channel temperature monitor IC. It contains it’s own local temperature sensor plus has the ability to monitor …

This is a small project to get you started with the electric imp and a Thermistor so you can see how you can get temperature readings updating live on a web site. This instruct able will address both the hardware and the web site along with all the parts in between. I’ve tried to keep …
This tiny breakout board carries Microchip’s 24LC512 EEPROM and MCP9802 temperature sensor devices, both of which support I2C protocol. This board can be used for both sensing the ambient temperature and storing it. The MCP9802 is a digital temperature sensor with an user-selectable resolution from 9 to 12 bit. It can measure temperature ranging from …
