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.

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.

It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 20 mA during navigation.\u003cbr\u003e\u003cbr\u003eTwo features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the the built in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dB sensitivity, but when you want to have a bigger antenna, you can attach an active antenna to the ANT pad. The module will automatically detect the active antenna and switch over!\u003cbr\u003e\u003cbr\u003eThe other cool feature of the new MTK3339-based module (which we have tested with great success) is the built in datalogging ability. Since there is a microcontroller inside the module, with some empty FLASH memory, the newest firmware now allows sending commands to do internal logging to that FLASH. The only thing is that you do need to have a microcontroller send the \"Start Logging\" command. However, after that message is sent, the microcontroller can go to sleep and does not need to wake up to talk to the GPS anymore to reduce power consumption. The time, date, longitude, latitude, and height is logged every 15 seconds and only when there is a fix. The internal FLASH can store about 16 hours of data, it will automatically append data so you don't have to worry about accidentally losing data if power is lost. It is not possible to change what is logged and how often, as its hardcoded into the module but we found that this arrangement covers many of the most common GPS datalogging requirements.\u003cbr\u003e\u003cbr\u003eWe've received reports from customers that have tested this version of the Ultimate GPS module in a high-altitude balloon, and it kept fix up to ~32km! There is a (theoretical, untested) firmware limit of 40Km. However, we provide no guarantee that it will work in all HAB's.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThis item is just the GPS module itself, no breakout board or other components included.\u003c\/strong\u003e The module can be soldered by hand without too much difficulty, we have it in our Eagle Library (GPS_FGPMMOPA6H) to make it easy to use.

The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing and output module. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted in to corresponding electrical signals when converging on the photoelectric detector. After being processed by the amplifier and signal processing circuit, the signal is converted in to a temperature value. The MLX90614 is self-calibrating and has a low noise amplifier integrated into the signal processing chip. The chip itself is a 17-bit ADC and DSP device, giving accurate and reliable results. \u003cbr\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cbr\u003eGravity: I2C Non-contact IR Temperature Sensor (MLX90614-DCI), due to its small field of view (FOV = 5°), is more suitable for industrial applications where the detection distance can be longer.
