Holder for two AAA batteries of small dimensions with a JST connector at the end that connects to a standard input for batteries. Often used with BBC micro:bit.

The MH-Z19 is a sensor that uses the non-dispersed infrared principle to detect CO2 in the air. It has built-in temperature compensation and high sensitivity to gas detection, and therefore has extremely accurate readings, and its outputs are on UART and PWM. It consumes little electricity and has a long service life.

NTC (Negative Temperature Coefficient) is a  resistor with variable resistance that changes depending on the temperature. The advantage of NTC is that it can measure a large temperature range, and measuring it with a voltage divider is very easy.

PMS7003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. This sensor can be used with different gadgets related to the concentration of particles in the air.

USB type C female connector for PCBs. This connector allows only power but not communication.

Where do we use flux? Flux is used by soldering. It is used to clean the pcb from any dust or oxidation (if there was any), which results with quality solder connections – solder attaches more easily to the pads where we want to put solder. Besides that, it improves electrical contact. Anyone who has tried it will know!

• Amount: 40g

Warning: Close the flux can after use.
