Raspberry Pi HATs

Designed for environmental monitoring, Enviro+ lets you measure air quality (pollutant gases and particles*), temperature, pressure, humidity, light, and noise level. Enviro+ is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it's small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten. Features BME280 temperature, pressure, humidity sensor (datasheet) LTR-559 light and proximity sensor (datasheet) MICS6814 analog gas sensor (datasheet) ADS1015 analog to digital converter (ADC) (datasheet) MEMS microphone (datasheet) 0.96' colour LCD (160 × 80) pHAT-format board Fully-assembled Compatible with all 40-pin header Raspberry Pi models Pinout Python library Citizen science air quality monitoring This board was developed in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten. Devices like Enviro+ allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The dataset gets better in quality every time an additional The more devices that contribute data, the better quality the dataset becomes. Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say 'the concentration of carbon monoxide is n parts per million', for example. Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro+ is really important to understanding the other data that Enviro+ outputs. You can implement Enviro+ in IoT applications as well. By connection it to Alexa you can get information about the temperature and humidity of the air by simply asking, or there's also an option to set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level etc. Software With the Python library you can control control all the parts of your Enviro+. There's a bunch of examples for each of the individual parts, an all-in-one example that shows you the data from Enviro+'s sensors in a visual way.

A meteorologically minded Raspberry Pi HAT designed to make hooking up weather sensors a breeze (or a squall, or a gale). Weather HAT is an 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 will let you easily attach wind and rain sensors. It will work with any Raspberry Pi with a 40-pin header. You could install it outside in a suitable weatherproof enclosure 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. 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 (optional) HAT-format board Fully-assembled Compatible with all 40-pin header Raspberry Pi models Downloads Python library Schematic Included Weather HAT 2 x 10 mm standoffs

When Raspberry Pi 4's system on chip (SoC) achieves a certain temperature, it lowers its operating speed to protect itself from harm. As a result, you don't get maximum performance from the single board computer. Fan SHIM is an affordable accessory that effectively eliminates thermal throttling and boosts the performance of RPi 4. It's quite easy to attach the fan SHIM to Raspberry pi: fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no soldering required! The fan can be controlled in software, so you can adjust it to your needs, for example, toggle it on when the CPU reaches a certain temperature etc. You can also program the LED as a visual indicator of the fan status. The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode. Features 30 mm 5 V DC fan 4,200 RPM 0.05 m³/min air flow 18.6 dB acoustic noise (whisper-quiet) Friction-fit header No soldering required RGB LED (APA102) Tactile switch Basic assembly required Compatible with Raspberry Pi 4 (and 3B+, 3A+) Python library and daemon Pinout Scope of delivery Fan SHIM PCB 30 mm 5 V DC fan with JST connector M2.5 nuts and bolts Assembly The assembly is really simple and almost takes no time With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers. Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts. Push the fan's JST connector into the socket on Fan SHIM. Software With the help of Python library you can control the fan (on/off), RGB LED, and switch. You'll also find a number of examples that demonstrate each feature, as well as a script to install a daemon (a computer program that runs as a background process) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.

Display HAT Mini features a bright 18-bit capable 320x240 pixel display with vibrant colours and formidable IPS viewing angles, connected via SPI. It's got four tactile buttons for interacting with your Raspberry Pi with your digits and a RGB LED for notifications. A QwST connector (Qwiic / STEMMA QT) and a Breakout Garden header is also squeezed in so it's a doddle to connect up different kinds of breakouts. It will work with any model of Raspberry Pi with a 40 pin header, but we think it goes with the Raspberry Pi Zero particularly well - we've included a pair of standoffs so you can use to bolt HAT and Raspberry Pi together to make a sturdy little unit. To accommodate the screen Display HAT Mini is a bit bigger than a standard mini HAT or pHAT – it's around 5 mm taller than a Raspberry Pi Zero (so a Mini HAT XL or a Mini HAT Pro, if you will). Display HAT Mini lets you turn a Raspberry Pi into a convenient IoT control panel, a tiny photo frame, digital art display or gif-box, or a desktop display for news headlines, tweets, or other info from online APIs. This screen is a handy 3:2 ratio, useful for retro gaming purposes!
