Description
Description:
GY-US42 is low cost, high-quality range range module.
Operating voltage 3-5 V, small power consumption, small size, easy installation.
Its principle of operation is that the probe emits ultrasonic waves irradiated by the measured object, the probe receives return sound waves, uses the time difference, calculates the actual distance. There are three ways to read the module data, i.e., serial UART (TTL level), IIC, pulse mode pwm,
The serial transmission speed is 9600bps and 115200bps, can be configured, there is a continuous, set the output in two ways, you can save the power settings.
IIC can modify the internal address to facilitate the IIC bus at the same time accessing several modules. The pulse pwm output is the same as sr04.
The module can be adapted to another working environment and connected directly to the microcontroller.
When the computer needs USB in the TTL module, a direct connection.
The IIC mode can be directly linked to APM, Pixhawk and other flight control.
Provides Arduino, 51, STM32 communication procedures of the microcontroller, does not provide circuits and internal microcontroller source.
As a result of using the transceiver an ultrasonic probe is built in, the range from the blind area is about 20 cm. Within 20 cm, the range is invalid.

DHT22- (Temperature and humidity sensor)
Product description:
The DHT22 module is designed to measure the temperature and humidity of the atmosphere. The difference from the younger model (DHT11), The DHT22 has a wide range and a high precision determination of temperature and humidity. The sensor works on the OneWire bus, which makes it possible to connect it to the Arduino only three wires ( two of which are POwer supply). Low power consumption allows you to install it on stand-alone devices.

MQ-8 (Hydrogen Gas Sensor Module)
MQ-8 Sensor Information: sensitive material MQ- 8 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity monitoring of other hydrogen-containing gas is also very good. The sensor can detect a variety of hydrogen-containing gas, in particular, city gas, is a low-cost sensor suitable for a variety of applications.

TTP 223B (Touch Thumb Sensor Module)
Product description:
This is a simple touch sensor module. You can use it to replace a traditional push button. Using the TTP223 touch detector IC It measures the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near it. This is the same technology used in the iPhone touch screen.This little sensor can "feel" people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it still can feel the touch. And the sensitivity well decrease as isolation get thick.
