DHT11 is a low cost humidity and temperature sensor with a 1-wire digital interface. Sensor comes factory calibrated and requires only 5K pull-up resistor connected to DATA pin to measure temperature and relative humidity.
LM335A is a very easy-to-use analog temperature sensor. The LM335A works like a Zener diode with a breakdown voltage proportional to absolute temperature at 10mV/°K. Hook up a resistor from 5V and GND, and the LM335A will output an analog voltage of 2.98V (298 Kelvin is 25C or room temperature). The output of the sensor is linear, and when calibrated at 25°C the LM335A has typically less than 1°C error over a 100°C temperature range. The sensor can operate continuously from −40°C to 100°C.
Calibration of the sensor requires a pot connected across the sensor, with the wiper of the potentiometer connected to the adjustment pin of the LM335.
Comes in a through-hole, TO-92 package.
The MCP9700 Linear Active Thermistor Intergrated Circuit (IC) is an analog temperature sensor that converts temperature to analog voltage. It's a low-cost, low-power sensor with an accuracy of +/-2 degrees Celsius from -40 degrees Celsius to +125 degrees Celsius while consuming only 6 μA of operating current.
Unlike resistive sensors (such as thermistors), the Linear Active Thermistor IC does not require an additional signal-conditioning circuit. Therefore, the biasing circuit development overhead for thermistor solutions can be avoided by implementing this low-cost device. The voltage output pin (VOUT) can be directly connected to the ADC input of a microcontroller. The MCP9700 temperature coefficients are scaled to provide a 1 degrees C / bit resolution for an 8-bit ADC value.
The MCP9700 provide a low-cost solution for applications that require measurement of temperature. This family is immune to the effects of parasitic capacitance and can drive large capacitive loads. This provides Printed Circuit Board (PCB) layout design flexibility by enabling the device to be remotely located from the microcontroller. Adding some capacitance at the output also helps the output transient response by reducing overshoots or undershoots. However, capacitive load is not required for sensor output stability.
PH302 is a photo diode with PIN structure. It has a wide photo receiving area and high speed response enabling applications for various remote controlling equipments. The resin material itself used for the package has filter effect to pass only infrared signals.
TFMS5XX0 IR Receivers series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses.
