Review of NODE, a multi-sensor on your smartphone

Today we are gonna to review this gluestick-like stuff.

Its name is NODE.

If I just show you the NODE, without telling you any things about it, I can guarantee that your blind guess can never be right.

It is a Bluetooth-connectable gadget that can connect with up to 2 sensors. And there is a wide choice of sensors; a whole lot of choice for sensors. Extracting the introduction of NODE from the official, it is a handheld sensor powerhouse with BLE 4.0 Smart supporting with different sensors. Each NODE can pair with two sensors at the same time.

They have 8 functions provided at this moment

CLIMA

The upper one is the CLIMA Module, the white sphere up there act as a mini, pocket observatory. It provides the measurement and recording of climatic information include Air Pressure, Light Index, Humidity and Temperature. It just gives you a chance to be a weatherman around your friends and colleagues. I’m sure you will become a weather-checking junkie after using the CLIMA.

OXA – CO2 & NO2 (not shown in picture)

The lower one is the OXA – CO2 Module, those tiny holes on the surface of the sensor help you to measure and record the carbon dioxide/nitrogen dioxide level around you. It is actually quite interesting to know about how good the air quality is throughout your daily life. Isn’t it?

Luckily, it shows that my working environment is within the CO2 safety level   
       

Well, this is empty and it is not an error NO2 level should remain zero or very low in normal environment

Now, just have a short summary of NODE, as a cutting edge gadget, NODE is really easy to use even for a novice. Install the apps, turn on your NODE and you can have fun with it. I won’t say NODE is kid-and-grandma-friendly, yet…it’s aimed for student or someone who want to get a taste on mini-scale scientific investigator.

The only real problem is that NODE and their sensors remain a relative high price (for any student to own one) even though it has been released about 2 years ago. What we can do is just to hope that, in one day, NODE will move to large production runs and price will come down hopefully.
