To check compatibility of a new remote with the receiver. Simply press the button on the remote, if the receiver flashes, but does not Triger the relay. The remote will be compatible, and you can start the programing process

To add a remote, press the button on receiver momentarily. The red light will come on. Then press the button on the remote that you want to program in. The red light will start flashing. After 4 flashes in will stop, and the button will be programmed in.

For the setting to take effect, the board needs to be disconnected from it’s power supply. The bellow settings will be done to the 3 headers and bridge pin on the receiver board, above the push button.

• With the header removed, the On button will switch the relay on, and the off button will in turn switch the relay off.
• With the header on Pin 1-2. Both Buttons will become momentary. And only hold the relay in place as long as they are pressed in.
• With the header on Pin 2-3. Each button will be able to switch the relay on and off individually. You will however not be able to switch the button off with the “off” button, if you switched it on with the “on” button. And vise versa.

Package Includes:

1 x Learning Code Receiver Relay
1 x Remote Control

As one of the smallest systems around there are so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. Introducing PiJuice! A fully uninterruptible power supply that will always keep your Raspberry Pi powered.

Our revolutionary PiAnywhere technology contained in every PiJuice HAT - is the best way to take your Pi off the grid! The real time clock (RTC) on board will let your Pi know what time it is even with no power input or internet connection. Alongside this is an integrated microcontroller (MCU) chip which will manage soft shut down functionality and a true low power deep sleep state and intelligent startup.

You will be able to always keep track of the charge levels and other info with the two built-in tri-coloured RGB LEDs, trigger events and scripts with the three programmable buttons and since the PiJuice will use up to just five of your GPIO pins (just power and I2C), the rest are free to diversify your project. The stacking header allows you to continue to use your existing HATs and add-ons with PiJuice.

Keep your Raspberry Pi running with solar, wind and other renewable power.

How to use Picamera with Raspberry Pi OS Bullseye: https://www.youtube.com/watch?v=E7KPSc_Xr24&list=WL&index=2

Description:

A sophisticated, hackable, 32x24 pixel thermal camera breakout! Use it to monitor the temperature of your CPU or coffee pot, or to build your own heat-seeking night vision camera. Works with Raspberry Pi or Arduino.

It's perfect for building into projects - industrial, scientific, or just fun - and much more affordable than most thermal cameras. Our breakout makes it easy to use the camera with your Raspberry Pi or Arduino, using I2C and 3-6V supply. And it's available in two different fields of view, 55° (standard) or 110° (wide angle) depending on your preference.

The MLX90640 far-infrared camera is an array of 768 (32x24) thermal sensors that can detect temperatures from -40 to 300°C with approximately 1°C accuracy and up to 64FPS! The applications of this camera are manifold: measure the heat or heat dissipation of devices like CPUs, circuit boards, or electrical appliances; use it to identify thermal inefficiencies in your home; or use it for presence detection to identify bodies in complete darkness.

Features

• Melexis MLX90640 far-infrared sensor array (datasheet)
• 32x24 pixels
• Field of view: 55°x35° or 110°x75°
• Up to 64FPS
• -40 to 300°C detection with approximately 1°C accuracy
• I2C interface (address 0x33)
• 3.3V or 5V compatible
• Reverse polarity protection
• Compatible with all models of Raspberry Pi, and with certain Arduino models

Kit includes

• MLX90640 breakout
• 1x5 male header
• 1x5 female right-angle header

We've designed this breakout board so that you can solder on the piece of right-angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).

Software

We've written software in C that you can use to generate images and video from the MLX90640 cameras.

SparkFun also provide an example Arduino/Processing sketch for the MLX90640.

Our software does not support Raspbian Wheezy.

Description

Ra-02 is a wireless transmission module based on SEMTECH's SX1278 wireless transceiver. It adopts advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters. It has strong ability of anti-jamming and has the function of air wake-up Consumption. Can be covering thousands of people in the district environment, particularly suitable for meter reading, smart home, burglar alarm equipment.

The LoRa series module Ra-01 is designed and developed by AI-THINKER Technology. The SX1278 RF module is mainly used for long-range spread spectrum communication. It can resist Minimize current consumption. Thanks to SEMTECH's patented LoRa ™ modulation technology, the SX1278 has a high sensitivity of -148 dBm with a power output of 20 dBm, a long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRa ™ modulation technology has obvious advantages in anti-blocking and selection, which solves the problem that the traditional design scheme can not consider the distance, interference and power consumption at the same time.

Features

• LoRa ™ Spread Spectrum modulation technology
• Constant RF power output at 20dBm-100mW voltage change
• High sensitivity: down to -148dBm
• Half-duplex SPI communication
• Programmable bit rates up to 300kbps
