You can change the communication way via the jumper cap on the shield. If all the three jumpers are connected to APC, the shield will realize the XBEE Bluetooth communication. If all jumpers are connected to 485, realize the RS485 communication function.

Onboard also comes with a reset button, a D13 indicator, and some common communication pins of 2.54mm pin pitch, such as serial port, IIC, and SPI communication pins.

Besides, it also has two 2pin terminal blocks. One is VIN GND terminal block, used to supply the external power for the UNO R3 control board, with an input voltage of DC 7-12V. The other is the Servo_PWR terminal block, used for VCC voltage input/output. If not connecting the external voltage, supply 5V for the shield; if connecting the external voltage, VCC voltage is actually the external input voltage.

The Spy Camera for Raspberry Pi is smaller than a thumbnail with a high enough resolution to see people, or ghosts, or whatever it is you're looking for. It's about the size of a cell phone camera - the module being just 8.5mm x 11.3mm - and has a stick-on back so it's easy to mount in a doorbell or behind a teddy bear's eye (might as well be creative!)

The camera comes with a 289mm (11.4") long cable so you can extend and mount your Pi away from the camera. Like the Raspberry Pi Camera Board, it attaches to your Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data.

The camera is connected to the BCM2835 processor on the Pi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi.

The sensor itself has a native resolution of 5 megapixel, and has a fixed focus lens onboard. In terms of still images, the camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30, 720p60 and 640x480p60/90 video.

CSI camera port works with Raspberry Pi 3/4 B

Want to build your own weather station? This sensor kit has a cup anemometer and wind vane to measure wind speed and direction and a tipping bucket style rain gauge, together with associated mounting hardware.

The sensors in this kit are active mechanical sensors that work by physically interacting with the wind and rain. They use magnets, reed switches and moving parts to produce simple signals that a microcontroller or single board computer can use to calculate wind speed, wind direction and rainfall.

The sensor cables are terminated in RJ11 connectors (each sensor only uses two wires though, so if you wanted you could snip off the ends and connect the wires to a different kind of connector). Armatures to mount the sensors are included, as well as a short metal mast that can be lashed to the top of a suitable pole with the included jubilee connectors.

Please note that this kit contains the mechanical wind and rain sensors only, and doesn't include any electronic components. You'll likely want to hook these sensors up to something like a Weather HAT (for Raspberry Pi), a weather:bit (for micro:bit) or a Weather Shield (for Arduino).

Features

• Three mechanical sensors: rain gauge, anemometer, and wind vane
• Passive electronics with sealed magnetic reed switches—no complex libraries required
• Rain gauge measures 0.011" (0.2794 mm) increments per bucket tip
• Anemometer detects wind speed with one switch closure per rotation (1.492 MPH = 1 closure/second)
• Wind vane reports direction as variable voltage; reliably resolves 8 cardinal directions
• Compatible with Arduino, ESP32, and other microcontrollers
• RJ11-terminated cables for clean, modular connections
• Minimal assembly required with standardized connectors
• Direct access to raw sensor data without proprietary protocols

Getting Started with Weather HAT

This comprehensive guide from RPi contains loads of detail on how to DIY your own weather station (it also contains lots of info about how these sensors work and how you can write code for them).

If you need pictures of how everything goes together, check out SparkFun's excellent hookup guide!

Datasheet

A meteorologically minded Raspberry Pi HAT designed to make hooking up weather sensors a breeze (or a squall, or a gale).

Weather HAT is a tidy all-in-one solution for hooking up climate and environmental sensors to a Raspberry Pi. It has a bright 1.54" LCD screen and four buttons for inputs. The onboard sensors can measure temperature, humidity, pressure and light. The sturdy RJ11 connectors (remember those?) will let you easily attach wind and rain sensors. It will work with any Raspberry Pi with a 40 pin header (that's most of them except the really old ones).

You could install it outside in a suitable weatherproof enclosure (like a waterproof junction box or even a Tupperware container) and connect to it wirelessly - logging the data locally or piping it into Weather Underground, a MQTT broker or a cloud service like Adafruit IO. Alternatively, you could house your weather Pi inside and run wires to your weather sensors outside - making use of the nice screen to display readouts.

Please note: the wind and rain sensors are sold separately.

Features

• 1.54" IPS LCD screen (240 x 240)
• Four user-controllable switches
• BME280 temperature, pressure, humidity sensor (datasheet)
• LTR-559 light and proximity sensor (datasheet)
• Nuvoton MS51 microcontroller with inbuilt 12-bit ADC (datasheet)
• RJ11 connectors for connecting wind and rain sensors (sold separately)
• HAT-format board
• Fully-assembled
• Compatible with all 40-pin header Raspberry Pi models
• Python library
• Schematic

Raspberry Pi and accessories are sold separately

Software

We've put together a Python library to give you easy access to all Weather HAT's functions, together with straightforward examples to help you learn how to read the sensors and use all the individual parts. There's also a weather station example that shows you how it's possible to combine all the functions into an application.

Our Getting Started tutorial contains a thorough walkthrough of Weather HAT's functionality plus beginner friendly instructions for installing the Python library and running the examples.

Notes

• Want to add on more I2C sensors? No problem, there's an solderless I2C header located on the back of the HAT that you can poke jumper / DuPont wires in to.
• If you'd like to hook up more analog sensors (3.3v max) we've broken out some extra ADC channels on the front of the board, as well as a convenient 3v3 power and ground.
• We've found two standoffs at the GPIO edge to be sufficient to keep this HAT firmly in place, but if you're attaching it to a full-size Pi and want to add standoffs at every corner you can pick up some more.
• Dimensions: 65 x 56.5 x 19 mm (L x W x H, including header and connectors)

This module adopts an 8-bit MCU as the main control chip, it can be applied in distance measurement, testing the performance of the HC-SR04 ultrasonic module. Plus, you can use this module in two ways since it supports Serial Port Display and Digital Tube Display.

How To Use

Measured distance can be displayed via the digital tube or serial port:

• Digital Display: directly connect ultrasonic sensor and provide 5V power supply (using wire jumpers or LiPo battery).
• Serial Port Output: connect the display module pins (VCC, TX, RX, GND) to USB to TTL converter pins (5V, RX, TX, GND) respectively. Select 9600 baud transmission rate and the output format is "D: XXX", where XXX represents the distance in centimeters.
