This module adapted for the arduino includes a laser diode and a 3-pin connector for a simple and quick adaptation with the Arduino. The diode is mainly used for laser toys, all kinds of level meter, instruments, stylus pen, mini LCD projector, remote listeners laser, alarm anti-theft light remote control. Light shots and different display can make the color of the image element a little different from the real object. The measurement allowed error is +/- 1-3 cm. Characteristic: - Supply voltage: 5VDC
- Connector of 3 pins:
1- GND
2- VCC
3- Light control of the laser diode
- Point mode: point facula
- Continuous output
- Operating temperature: -36 ° C - + 65 ° C
- Laser wavelength: 650nm (red)

The module uses a 24-bit high precision A/D conversion chip HX711.
The input circuit can be configured to provide a bridge.
The electric bridge voltage sensor model (such as pressure, weight) is an ideal sampling module with high precision and low cost. HX711 Module Weighing Pressure Sensor 24 Bits features:
- Two selectable differential input channels
- Active low noise PGA with selectable gain of 32, 64 and 128
- Power supply regulator for load cell and ADC analog power supply
- Oscillator on chip that does not require external component with optional external glass
- Power-on-reset on the chip
- Simple serial control and serial interface: controls driven by pins, programming is not required
- Output data rate 10SPS or 80SPS selectable

You can easily control any device over the Internet through your phone, computer, etc.
The module can handle 5 users at the same time, it can work in two modes: STA (client) and AP (access point).
In AP mode, the module is connected via WIFI directly to your phone or computer (in open field can be up to 300 meters).
In STA mode, the relay module is connected to the access point (router) that supplies the network.
Wi-Fi in the room where the relays are located. In this case, the range mainly depends on the power of the access point antennas (routers).
You should not turn off after the configuration is completed, as some of the parameters of the WIFI module cannot be saved when power is cut off.
