Measure hydrogen fluoride concentration with a factory-calibrated electrochemical probe that supports analogue, I2C and UART output modes. It is designed for quickly building an HF concentration detector for industria...

SKU: DF-SEN0469 | Brand: DFRobot

This calibrated gas sensor measures ammonia concentration in the environment using an electrochemical probe. It supports three output modes — analogue, I2C and UART — so it can slot into a wide range of microcontrolle...

SKU: SF-SEN-28869 | Brand: SparkFun

This anemometer measures wind speed using rotating cups that turn an enclosed magnet. On each rotation, the magnet closes a reed switch, producing a simple pulse output that can be counted by your electronics.The outp...

SKU: SF-SEN-28867 | Brand: SparkFun

This rain gauge measures rainfall using a self-emptying bucket-type mechanism. Each time enough rain is collected, it triggers a momentary button closure that can be read by your electronics project.The switch closure...

SKU: SF-SEN-29758 | Brand: SparkFun

This surface-mount air velocity module uses a MEMS thermopile-based sensor to measure airflow in compact electronic assemblies. It is designed for low-profile enclosures where board space and height are limited.The FS...

SKU: SF-COM-21506 | Brand: SparkFun

The ZMOD4450 is a compact gas sensor module for detecting gases associated with food ripening or rotting. It is intended for refrigeration air quality (RAQ) applications such as food storage and shipping, including hu...
