Highlights: By adjusting the potentiometer can set the length of time. MicroUSB 5.0V power supply with an input port, easy to use. 5 ~ 30V wide supply voltage. External signaltrigger and keytriggerin two ways. With a relay indicator. Anti-interference ability, the relay at various interference will not misoperation, suitable for industrial control.

The official Raspberry Pi 3 case in a stunning Red & white design Optional clip-on lid provides protection but can be removed if using a HAT All primary ports (including micro SD) accessible Removable side plate allows access to those wonderful GPIO pins Snug and secure fit.

Introduction: These 3-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Technical Details: Technical specs: Usable temperature range: -5° to 90°C (-23°F to 194°F) 9 to 12 bit selectable resolution Uses 1-Wire interface- requires only one digital pin for communication Unique 64 bit ID burned into chip Multiple sensors can share one pin ±0.5°C Accuracy from -10°C to 85°C Temperature-limit alarm system Query time is less than 750ms Usable with 3.0V to 5.5V power/data

The USB to RS485 module is a cost-effective way to convert RS485 industrial buses to a USB interface. When connected to a PC USB port the USB to RS485 module is automatically detected and is installed as a native COM port which is compatible with any existing serial communication application. Multiple modules can be installed when using USB hubs thus allowing a hassle-free configuration of a multi serial system. Features

• Reliable RS485 link
• Automatic Switching between Transmit/Receive mode of RS485.
• Twisted pair cable can work upto 1.2 Km distance.
• Ground Output for wire shielding.
• USB Powered
• USB Port Plugabble type
• Designed for industrial environment

Specifications

• Any baud rate from 1200 bps to 115 kbps
• Current: 100mA current at 5V DC taken from PC’s USB Port
• Modes: RS-485 Half Duplex (2-wire)
• Built in terminal resistor of 120R Ohm
• Length of twisted pair cable maximum can be 1.2 Km (Kilometer) Maximum
• Cable type for optimal range: Two core, Twisted Pair Shielded type, D and D- should be twisted with each other to get optimal range

Description: This Ceramic Piezo Vibration Piece Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vibration. When the piezoelectric ceramic shocking will generate an electrical signal, Arduino Controller analog port can be perceived slight vibration signals, Also can be realized with vibration interactions related works, such as electronic drums. Marking "A" represents the module is a Analog Sensor, the other side graph represents function of the sensor. Easy identification!
