A Dual Temperature Display With Humidity Measurement

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.

Working With LM19 Temperature Sensor

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’ »
