Photoresistor LDR CDS 5mm GL5516

In pitch-black conditions, the photocell’s resistance will be in the megaohm’s (1.0MΩ+) range. Shining an LED on the sensor can drop the resistance to near-zero, but usually the resistance of the photocell falls between 8-20kΩ in normal lighting conditions.

By combining the photocell with a static resistor to create a voltage divider, you can produce a variable voltage that can be read by a microcontroller’s analog-to-digital converter.

MCP9700A-E/TO 9700 Low-Power Linear Active Thermistor Sensor Microchip
Linear Active Thermistor™ ICs are sensors whose output voltage is directly proportional to measured temperature. The MCP9700 can accurately measure temperature from -40C to +150C. The output of the MCP9700 is calibrated to a slope of 10mV/°C and has a DC offset of 500mV. The offset allows reading negative temperatures without the need for a negative supply. The MCP9700 is packaged in space saving 5-pin SC-70 packages, making it ideal for space-critical and low-cost applications.
