LM92 is a 12-bit + sign temperature sensor from Texas Instruments. This sensor operates on the I2C interface and can achieve an accuracy as high as ± 0.33 °C within the typical temperature measurement range. I created a comprehensive Arduino library for this sensor (the library can be downloaded towards the end) and in this post I will explain each of the functions in detail.

LM95172 is a 13 to 16 bits wide temperature range automotive-grade temperature sensor in a ceramic SOIC package. Besides its wide range temperature measurements capability (-40 Celsius to 200 Celsius), it can also be programmed to trigger over-temperature/under-temperature alarms and perform one-shot temperature conversation for low power applications.

I have built quite a few (1,2,3) temperature measurement circuits in the past, but none of those has remote sensing capability. So I decided to make a wireless temperature sensor so that temperature measurements can be made anywhere within the range of the transmitter and the receiver.

I built a digital thermometer a couple of weeks ago. This thermometer uses an LM19 sensor calibrated for measuring a wide temperature range (-55 – 130 Celsius, -67 – 266 Fahrenheit) for outdoor temperature measurement and an SHT21 digital thermometer with humidity measurement for indoor use.

The DS7505 digital thermometer and thermostat is a very versatile temperature sensor. It offers 9 to 12-bit digital temperature readings between -55 and +125 Celsius with an accuracy of 0.5 degree. It can be used with any MCUs that has I2C support or can be pre-programmed and used in standalone applications as digital thermostats. Continue reading ‘Interfacing DS7505’ »
LM19 is an analog temperature sensor that operates over a while temperature range (-55 to 130 Celsius). It is very easy to interface it with a microcontroller due to is fairly linear voltage output. Continue reading ‘Working With LM19 Temperature Sensor’ »
