Corrosion resistant capacitive soil moisture sensor. It can be supplied with voltage from 3.3 to 5.5V. Depending of the humidity level, the analog output has a voltage in the range of 0-3V.

Simple to use VOC sensor. Detects alcohols, aldehydes, ketones, organic acids, amines, aliphatic and aromatic hydrocarbons. On this basis, it calculates the equivalent level of carbon dioxide (eCO2).

Universal OLED display with sharp and bright pixels.

USB to Serial cable, Serial (UART) connector not in FTDI standard, just 4 flexible female pins.

Nickel plated brass hex spacer 30 mm, Female-Female, M3,

Pogo pins are little spring-loaded contacts, very handy for making jigs, or making momentary (but electrically solid) contacts. Useful when You need to test many identical boards.
