The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Since it has a Linear + 10.0 mV/°C scale factor it is very easy to calculate temperature value.
Digital Capacitive Touch Switch Module is based on TTP223B. Normally, it outputs low and keeps at a low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the quick response state. When not being touched for 12 seconds, it switches to a low power state again. If the module is mounted on the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.
2-Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. It uses a low level triggered control signal (3.3-5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts. It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to control a high-current circuit with a low-current signal.5V relay signal input voltage range, 0-5V. VCC power to the system. JD-VCC relay in the power supply. JD-VCC and VCC can be shorted.
This MT3608 DC-DC Step Up Power Booster Module is a low-cost module that can step-up a 2 to 24V input voltage up to a 5 to 28V output at up to 2A. The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard. DC-DC boost converters step up the input voltage to a higher voltage while also stepping down the available current since the module can’t output more power than its inputs. This boost converter is adjustable and capable of outputting a voltage in the range of 5.0 to 28V at a continuous current of up to 1.5A depending on input/output voltage settings with 1A available with most settings.
