Inputs
- GND – This is where you connect the low side of the voltage you are measuring. Caution! : This is the same electrical point as your Arduino ground.
- VCC: The is where you connect the high side of the voltage you are measuring
Outputs
- S: This connects to your Arduino analog input.
- – (or minus): This connects to your Arduino ground.
- : This is not connected. It does absolutely nothing.

HX711 is a precision 24-bit analog to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32. -

SIM808 module is a GSM and GPS two-in-one function module. It is based on the latest GSM/GPS module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation. It features ultra-low power consumption in sleep mode and integrated with charging circuit for Li-Ion batteries, that make it get a super long standby time and convenient for projects that use rechargeable Li-Ion battery. It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver channels. Besides, it also supports A-GPS that available for indoor localization. -
Features :- Ready to plug & play.
- It can connect to various modules like sensors, servos, relays, buttons, potentiometers
- Each functional module has buckled port with VCC, GND and Output, which has corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.

Features: -With relay output, this module is used to detect the humidity and control related the device power directly. -This product make use of HR202 humidity sensor. -The comparator outputs drive relays directly. It connects to 220V AC or other devices. -With leads, sensor interface can be installed with pin. -It's easy to install with 4 0.3cm fixing bolt hole. -When ambient humidity exceeds the setting threshold value the relay sucks and shuts, what's more, the common terminal connects to the start. -If the ambient humidity below the setting threshold value, the situation will be counter. -Common, normally open and normally closed the three ports are equivalent to a dual-control switch. -When the relay coil is electrified, the common will connect to the normally open, otherwise, the common will connect to normally closed.
