Feature: Internal with logic level conversion circuit. No need external 5V level to turn into a 3.3V level The power input port with anti-anti-circuit. To avoid accidental power plug reversed, leading to the module burned HM-10, HM-11 series Bluetooth module using TI CC2540 chip, configuration 256Kb space, support AT commands, you can change the role (master and slave mode) and the baud rate, the device name, Pairing password and other parameters, convenient and flexible.

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.

Product Description: The MPU6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon together with an onboard Digital Motion Processor (DMP) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. The devices are offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000? family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space constrained boards. The InvenSense Motion Apps Platform that comes with the MPU-6050 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development. For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.

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.

The SRF05 is an evolutionary step from the SRF04, and has been designed to increase flexibility, increase range, and to reduce costs still further. As such, the SRF05 is fully compatible with the SRF04. Range is increased from 3 meters to 4 meters. A new operating mode (tying the mode pin to ground) allows the SRF05 to use a single pin for both trigger and echo, thereby saving valuable pins on your controller. When the mode pin is left unconnected, the SRF05 operates with separate trigger and echo pins, like the SRF04. The SRF05 includes a small delay before the echo pulse to give slower controllers such as the Basic Stamp and Picaxe time to execute their pulse in commands

This bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
