pH measurement probe that ends electrically in a BNC connector, suitable for use with most pH meters and controllers with a BNC input (not included). This probe can be used for a wide range of applications such as aquariums, hydroponics, laboratory work, etc.

Module for measuring the pH level and the temperature of a water-based solution.

Reflectance sensor made up of an infrared emitter diode and a phototransistor

Made up of a probe with two metal terminals and a small module based on the LM393 IC, it measures the moisture content of the soil, for example in a flower pot

Module with a microphone that picks up the sound level of the surrounding environment

Fully calibrated and with an SPI digital output, this sensor measures temperatures from -40°C to +70°C and relative humidity from 10% to 98%

Module fitted with a reflective infrared sensor (ST188), an LM393 voltage comparator, a sensitivity adjustment trimmer and both analogue and digital outputs

Module with 4 white LEDs, built around the TAOS TCS3200 chip, a light-to-frequency colour converter

Breakout board built around the tiny TMP102 digital temperature sensor
