Adafruit BME680 - Temperature, Humidity, Pressure and Gas Sensor
The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular CCS811 and BME280 ICs.
SPL06-001 Barometric Height Sensor Module for Drones (resolution up to 5 cm)
The state-of-the-art BME680 breakout lets you measure temperature, pressure, humidity, and indoor air quality, and is Raspberry Pi and Arduino-compatible!
This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~50k. The sensor itself is thin and flexible, but the resistance does not change while being flexed.
This pressure sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1.5 Pascal resolution, which can resolve altitude at 0.3 meters (compare to the BMP180 which can do 0.17m).
LPS25HB Pressure/Altitude Sensor Carrier with Voltage Regulator This carrier for ST’s LPS25HB digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute accuracy down to ±0.2 mbar (0.02 kPa) and typical RMS noise of 0.01 mbar (1 Pa) in high-resolution mode.
This breakout board is the simplest way to create a project with mutiple capacitive touch sensors. No microcontroller is required here just power with 1.8 to 5.5VDC and connect up to 5 conductive pads to the 5 left-hand pins.
This chip is good for use with power and logic voltages ranging from 2.4V to 5.5V so you can use it with your 3V or 5V microcontroller. There's a basic temperature sensor inside but there's no specifications in the datasheet so we're not sure how accurate it is.
This carrier for ST’s LPS331AP digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute pressure accuracy over temperature down to ±2 mbar (0.2 kPa) and typical RMS noise of 0.02 mbar (0.002 kPa) in high-resolution mode.
With this sensor, you can determine the depth of water by measuring the pressure. It has a low power consumption, a resolution of approx. 2 mm and can measure pressures from 0 to 30 bar.
Unlike most ported pressure sensors, this one uses I2C, it's really easy to use with any microcontroller.
