TMP36 Temperature Sensor Features The TMP36 sensor is used to measure temperature from -40°C to +125°C and its tolerance threshold is +150°C. This sensor is calibrated directly on Celsius and its accuracy is 2°C. This sensor has an analog output. The output voltage changes linearly as the temperature changew. For example, the sensor output voltage is 0.75 volts at 25°C and 2.7 volts at 125°C.This sensor can be used in environmental control systems, thermal protection, fire alarms, CPU thermal m...

TLP281 4-Channel Opto-isolator IC Module Features Sometimes we need to separate the low-voltage section (microcontroller) from the high-voltage one in circuit in order to prevent noise and damage to the microcontroller. This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC. This IC contains 4 LEDs (Light Emitting Diode). 4 high-voltage channels can be controlled by microcontroller using this IC.This module can also be used to turn on and off the servo motor and oth...

LJ12A3-4-Z/BX Inductive Proximity Sensor Features Proximity sensors are used to detect the presence of nearby objects. The LJ12A3-4-Z / BX sensor has three pins, two of which are connected to a supply voltage of 6 to 36 V. The output pin is PNP and NO (Normal Open). That is, it is normally Low and when it detects an object, it becomes HIGH. The detection distance is 4 mm, and it can only detect metal objects such as copper, aluminum, iron, etc. Note Since the operation voltage is more than 5 V,...

L298P Motor Driver Shield Features Today, DC motors are used in the manufacturing many tools and equipments. So, speed and direction control of these motors is very common. A half-bridge circuit is one of the simplest methods to control a DC motor. This method not only controls the motor direction, but also can be used for speed control. This shield is based on L298P IC. The most important features are: Control two DC motors simultaneously with voltage 4.8 to 24V and up to 2A current Schottky diodes ...
