The TSL2591 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low-cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain\/timing ranges to detect light ranges from 188 uLux up to 88,000 Lux on the fly.\u003c\/p\u003e\n\u003cp\u003eThe best part of this sensor is that it contains both infrared and full-spectrum diodes! That means you can separately measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes) This sensor is much like the TSL2561 but with a wider range (and the interface code is different). This sensor has a massive 600,000,000:1 dynamic range! Unlike the TSL2561 you cannot change the I2C address, so keep that in mind.\u003c\/p\u003e\n\u003cp\u003eThe built-in ADC means you can use this with any microcontroller, even if it doesn't have analogue inputs. The current draw is extremely low, so it's great for low-power data-logging systems. about 0.4mA when actively sensing, and less than 5 uA when in power-down mode.\u003c\/p\u003e\n\u003cp\u003eAs if that weren't enough, we've also added SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder. Just wire up to your favourite micro with a plug-and-play cable to get data ASAP. For a no-solder experience, just wire up to your favourite micro using a STEMMA QT adapter cable. The Stemma QT connectors also mean the TSL2591 can be used with our various associated accessories. \u003cstrong\u003eQT Cable is NOT included\u003c\/strong\u003e, but we have a variety in the shop.\u003c\/p\u003e\n\u003cp\u003eOf course, we wouldn't leave you with a datasheet and a \"good luck!\" - we wrote a detailed tutorial showing how to wire up the sensor, use it with an Arduino and example code that gets readings and calculates lux.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eRevision History:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of September 18, 2024\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- We've added a jumper to the LED and updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of Sept 16, 2020\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e- We've updated this sensor to our 0.7\" x 1.0\" STEMMA QT standard for sensors.

This chip can handle up to 12 individual touchpads.\u003c\/p\u003e\n\u003cp\u003eThe MPR121 has support for only I2C, which can be implemented with nearly any microcontroller. You can select one of 4 addresses with the ADDR pin, for a total of 48 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analogue inputs: it handles all the filtering for you and can be configured for more\/less sensitivity.\u003c\/p\u003e\n\u003cp\u003eThis sensor comes as a tiny hard-to-solder chip so we put it onto a breakout board for you. Since it's a 3V-only chip, we added a 3V regulator and I2C level shifting so it's safe to use with any 3V or 5V microcontroller\/processor like Arduino. We even added an LED onto the IRQ line so it will blink when touches are detected, making debugging by sight a bit easier on you. Comes with a fully assembled board, and a stick of 0.1\" header so you can plug it into a breadboard. For contacts, we suggest using copper foil or pyralux, then solder a wire that connects from the foil pad to the breakout.\u003c\/p\u003e\n\u003cp\u003eGetting started is a breeze with our Arduino library and tutorial.

Or, rather, are you convinced that your house is haunted but have never been able to prove it since you've never had a camera small enough that the ghosts wouldn't notice it? Or maybe you want to put a camera on your cat to see what she's up to during the day. Or make a 'life capture' camera that takes a time-lapse of your day. A tiny little camera is whatcha need!\u003cbr\u003e\u003cbr\u003eThis \u003cstrong\u003eMini Spy Camera\u003c\/strong\u003e 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 fairly high resolution (480p video and 1280x720 photo) module, with a driver board that is about 1 square inch in size, with a microSD card holder. The image module is about the size of a cell phone camera - the body being just 6.2mm x 6.2mm - 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). There's a power LED and an 'activity' LED that lets you know what its doing.\u003c\/p\u003e\u003cp\u003eWe don't have a real datasheet, we think these are just 'guts' of some low cost keychain camera. However, it's not too hard to use. Connect the red wire to 3.7V-5VDC and the black wire to ground. Then use the \u003cem\u003ewhite\u003c\/em\u003e wire to control the camera. When touched to ground for under about 100ms, the camera will take a photo and stick it in a PHOTO folder on the SD card, numbered from PIC000.jpg up to PIC999.jpg. The red LED will blink briefly. When the trigger wire is touched for over 100ms, it will start taking a video clip with audio from the mini microphone. The LED will stay on during the entire recording. Touch it again for half a second+ to stop.\u003c\/p\u003e\u003cp\u003eWhat we like about this module is it's simplicity and good quality. Best of all, there's no overlay text like most other cheap modules. It's really easy to make a micro-timelapse device (see the video above for a timelapse we made with a simple Arduino pulsing the trigger pin every 30 seconds), or make little videos from the point of view of your robot! Note that there is a microphone but the audio quality is a little buzzy, it works but we're not going to replace our goPro or cellphone camera here.\u003c\/p\u003e\u003cp\u003eIn terms of still images, the camera is capable of 1280x720 pixel static images, and 640x480 video.
