Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is - you can tell how an object is moving!) As these sensors become more popular and easier to manufacture, the prices for them have dropped to the point where you can easily afford a triple-axis gyro! Only a decade ago, this space-tech sensor would have been hundreds of dollars.\u003c\/p\u003e\n\u003cp\u003eThis breakout board is based on the latest gyro technology, the L3GD20H from STMicro. It's the upgrade to the L3G4200 (see this app note on what to look for if upgrading an existing design to the L3GD20) with three full axes of sensing. The chip can be set to ±250, ±500, or ±2000 degree-per-second scale for a large range of sensitivity. There's also built-in high and low pass sensing to make data processing easier. The chip supports both I2C and SPI so you can interface with any microcontroller easily.\u003c\/p\u003e\n\u003cp\u003eSince this chip is a 3.3V max device, but many of our customers want to use it with an Arduino, we soldered it to a breakout board with level-shifting circuitry so you can use the I2C or SPI interface safely using a 5V interface device. We also place a 3.3V regulator on there so you can power it from 5V.\u003c\/p\u003e\n\u003cp\u003eSince we expect people will want to attach it firmly to their project, the PCB comes with four 2.1mm mounting holes. Use #2-56 imperial or M2 screws screws.\u003c\/p\u003e\n\u003cp\u003eGetting started is easy - simply connect SDA to your Arduino I2C data pin (On the UNO this is A4), SCL to I2C clock (Uno: A5), GND to ground, and Vin to 3 or 5VDC. Then install and run our easy-to-use Arduino library, which will print out the XYZ sensor data to the serial terminal.

Like a classic electret mic, it converts sound into a voltage signal, but because it’s a MEMS mic, it doesn’t need an external bias resistor or amplifier — it’s all built in. The onboard microphone is the SPW2430, a small, low-cost option with a 100Hz to 10kHz response range, making it a great fit for general audio capture and detection.\u003c\/p\u003e\n\u003cp\u003eThis Adafruit breakout works well for projects like voice changers, audio recording\/sampling, and audio-reactive builds using FFT. To keep the board compact and simple, it includes only a 3V voltage regulator (the mic requires 3.3V DC) and filter capacitors — there’s no additional op-amp. The output has a 0.67V DC bias, with around 100mV peak-to-peak when speaking close to the mic, which suits line-level style inputs without clipping. For louder sounds, the output can reach up to 1V peak-to-peak. If you need adjustable gain or auto-gain control, it’s better to use one of the mic + amplifier options, or add a rail-to-rail op-amp and resistors if you want more output swing.\u003c\/p\u003e\n\u003cp\u003eWiring is straightforward: connect GND to ground and Vin to 3.3–5V DC. For best results, use the quietest power supply available (on an Arduino, that’s usually the 3.3V rail). The audio waveform is available on the DC pin, which sits at about 0.67V when quiet (with a little drift). If your audio equipment needs AC-coupled audio, you can use the AC pin, which has a 10µF capacitor in series.\u003c\/p\u003e\n\u003cp\u003eThe output isn’t meant to drive speakers (or anything beyond the smallest in-ear headphones). If you want to connect to speakers, you’ll need an external audio amplifier, such as a 3.7W stereo amp.

Inside is a silicone-gel covered pressure sensing gauge with a pre-calibrated and compensated 24 bit ADC. We have example code and libraries for Arduino or CircuitPython\/Python. You can measure absolute pressure 0 to 25 PSI, which is a great range since ambient pressure here on Earth is about 14.5 PSI.\u003c\/p\u003e\u003cp\u003eThe port is made of stainless steel and is 3.7mm long and 2.5mm diameter. It doesn't come with tubing so be sure to purchase some tubing to attach to the port.\u003c\/p\u003e\u003cp\u003eWe've placed this nice sensor on a breakout board with 3.3V power regulation and level shifting so you can use it with any kind of microcontroller or microcomputer, from an Arduino compatible to Raspberry Pi\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eUses I2C address 0x18\u003c\/li\u003e\n\u003cli\u003e0 to 25 absolute PSI measurement range\u003c\/li\u003e\n\u003cli\u003eApp notes and datasheets for Honeywell MPR series micro pressure sensors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 17.8mm x 16.7mm x 7.5mm \/ 0.7\" x 0.7\" x 0.3\" \u003c\/p\u003e\n\u003cp\u003eProduct Weight: 1.1g \/ 0.0oz \u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":46982537445548,"sku":"jpd1787257847878","price":21.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/3858\/0140\/files\/adafruit-mprls-ported-pressure-sensor-breakout---0-to-25-psi_1.jpg?v=1787257857"}],"url":"https:\/\/findnuvorio.com\/collections\/sensors.oembed","provider":"Findnuvorio","version":"1.0","type":"link"}
