Precision Cooker: A Temperature Controlled Cooker Using Atmega

Leave a Comment / Uncategorized, Using Atmega / By

Precise time and temperature control are critical when cooking. Slight deviations in either temperature or cooking time can ruin delicate ingredients. Despite this fact, most modern day stovetops provide no data regarding their current temperatures and do not have built in timers. The stovetops that do provide these functionalities are often expensive and require specialized …

Clinical-grade human body temperature sensor has ±0.1°C accuracy

Leave a Comment / Tech News Updates / By

Description The MAX30205 temperature sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analog-to-digital converter (ADC). Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. Communication is through an I2C-compatible 2-wire serial interface. The I2C …

A Temperature Logger to Protect Sea turtles

Leave a Comment / Tech News Updates / By

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 …

Temperature Measurement with NTC Thermistors

Leave a Comment / Tech News Updates / By

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 …
