IoTSeeker Passwords seeker

It is very good to know the basic basic hack techniques. 

Anyone who knows them usually acts a little wiser or clever.

Co se naučíte, když si pustíte video přednášky dvojnásobnou rychlostí? Víc než si nejspíš myslíte


Senzory CO2_eq a VOC z oxidu kovů

Senzor obsahuje snímací element vyrobený z oxidu kovů (MOX), který je polovodič typu n, snímacích elektrod a ohřívače. Nejčastěji používaným MOX je v současnosti SnO2. Snímací prvek se zahřívá na optimální teplotu pro detekci cílového plynu. Typická teplota je v rozsahu 200 až 400°C.

Kyslík z atmosféry se adsorbuje na snímacím elementu, váže jeho elektrony a vede tak k tvorbě ochuzené vrstvy. Pokud jsou v okolní atmosféře přítomny i molekuly oxidačních nebo redukčních plynů, mohou reagovat s adsorbovanými ionty kyslíku a dříve vázané elektrony jsou opět dostupné jako nosiče náboje ve snímacím elementu. Toto vede ke snížení energetické bariéry v pásovém modelu polovodiče, což se projeví zvýšením vodivosti.

Senzor aerosolových částic SPS30

Princip činnosti

Senzory využívají vlastnosti světla rozptýleného na částici k měření počtu, velikosti a koncentrace částic. Základní komponenty jsou: zdroj světla namířený na částice, detektor měřící světlo rozptýlené částicí a elektronické obvody, které zpracovávají a analyzují výstup z detektoru...




Senzory rozdílu tlaků

Princip činnosti

Senzor rozdílu tlaků (link is external) používá MEMS kalorimetrický mikrosenzor. Snímací element se skládá ze dvou snímačů teploty a malého vyhřívacího elementu. Rozdíl teplot naměřený senzory koresponduje s hmotnostním průtokem protékajícím čipem...

Feeding power to Arduino - WeMos: the ultimate guide

Feeding power to Arduino - WeMos: the ultimate guide



Four ways to power up the Arduino Uno

• An Arduino Uno board (Rev 3)

• Standard A-B USB cable

• AC to DC Adapter (7-12V)

• Batteries (9V) with a battery connector

• Jumper wires (Female to Male)

Feeding power to Arduino: the ultimate guide - unknown
www.open-electronics.org


... for example for no reason it will be possible to apply voltages exceeding the 5 V socket even by a single Volt, since the board’s integrated circuits would burn immediately ...



Battery Powering Arduino Uno




Powering Arduino With a Battery

Make your Arduino projects portable by using a battery for power. From the Uno and Mega documentation pages:

"The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable.
If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts." ...
