SKU: SF-SEN-00245

The DS18B20 is a digital temperature sensor from Maxim (now Analog Devices) that communicates over a 1-Wire bus. It reports temperature in degrees Celsius with 9 to 12-bit configurable resolution. Each sensor has a unique 64-bit serial number, allowing multiple sensors to share a single data line...

SKU: AF-1727

The MAX31850K breakout board is a 1-Wire thermocouple amplifier with cold-junction compensation for K-type thermocouples. Unlike SPI-based amplifiers, the 1-Wire interface allows any number of thermocouple breakouts to share a single data line — ideal for multi-point temperature measurement. The...

The SparkFun PCA9306 Level Translator Breakout provides dual bidirectional voltage-level translation for I2C and SMBus lines. It lets you safely connect devices operating at different logic levels — for example, a 3.3V sensor to a 5V microcontroller — without a direction pin. Simply apply your re...

SKU: SF-SEN-13879

The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be...

SKU: SF-BOB-13906

The SparkFun Multiplexer Breakout provides access to all pins and features of the 74HC4051, an 8-channel analog multiplexer/demultiplexer. The 74HC4051 allows you to turn four I/O pins into eight multifunctional, individually selectable signals, which can be used to do everything from driving eig...

SKU: SF-SEN-16476

The SparkFun Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's MPR Series piezoresistive silicon pressure sensor. This MicroPressure Sensor offers a wide pressure sensing range of 60mbar to 2.5bar, easy to read 24 bit digital I2C output, and can be calibrated and compen...

SKU: SF-SEN-15440

The BME280 Atmospheric Sensor Breakout measures barometric pressure, relative humidity, and temperature from a single compact board. With both Qwiic (I2C) and 0.1″ header connections, it integrates easily into Arduino, Raspberry Pi, and other microcontroller projects — no soldering required when ...

SKU: SF-SEN-11084

Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high resolution 24-bit ADC and transmitted over I2C, meaning it’s easy to interface with ...

SKU: SF-DEV-19217

We carry several data logging products which have microSD sockets on them: OpenLog Artemis and the Qwiic OpenLog to name but two. They're great for logging data to a microSD card, but when it comes to reading the logged data quickly you usually have to pop out the microSD card and plug it into yo...
