We are going to set up an indoor air quality monitoring system. And this Grove – air quality sensor is just in time. This one is a multifunctional one, and you can keep alcohol, carbon monoxide, acetone, thinner, formaldehyde and other slightly toxic gases under control with this all-in-one sensor.
Car stays one of the hottest topics among people. However hacks on car get trapped by power somehow. That’s why we prepare this high current CPT-C5 power converter 12V/24V switch to 5V. The output current can be high up to 5A! Now nothing can stop you from power up a real project in a car!
And next, we have this light and convenient 13.56MHz RFID book tag. Use it like a sticker, and post it upon anywhere that you would love to make some identification, for example, books, goods and something else. To make a whole solution, you will also need a RFID reader, such as NFC Smart Card Reader that fulfills the read-and-write function. And the last, we have Probe jumper wire – 8pcs at hand. We can’t store much cables because needs for different cables keep popping up. So here we have another kind of cable with two probes on each side. Find it useful? Just stock some on your table.
