2.4 GHz 10 Channel Remote Control Switch

Sa post na ito magtatayo kami ng isang 10 channel remote control switch batay sa ISM (pang-industriya, Siyentipiko at Medikal) na banda.

Panimula

Ang Banda ng ISM ay pinamamahalaan sa 2.4 GHz, na maaaring magamit nang walang paglilisensya na may makatwirang output ng kuryente.

Ang iminungkahing proyekto ay pangkalahatang layunin ON / OFF wireless switch, na maaaring magamit upang i-ON / OFF ang mga ilaw, tagahanga, gamit sa bahay sa awtomatiko sa bahay kung may sapat na tiwala na magdala ng mga pagbabago sa hardware o software sa proyektong ito.

Ang proyekto ay nahahati sa dalawang bahagi: Ang remote at ang receiver.

Ang Remote Controller:

Ang remote control ay binubuo ng 10 mga pindutan ng push para sa pagkontrol ng 10 indibidwal na mga relay sa tatanggap. Ang remote ay pinamamahalaan ng 9V na baterya na ginagawang portable.

Ang Puso ng proyekto ng ay 2.4 GHz transceiver module NRF24L01 na ginagawang posible ang komunikasyon sa pagitan ng dalawang Arduinos.

Ang Remote isport isang pagkilala LED.

Ang LED ng pagkilala ay mag-iilaw pansamantala sa bawat oras na pinindot namin ang isang pindutan sa malayuang at kung ang naihatid na signal ay natanggap ng tatanggap at pagkatapos ay ang tagatanggap ay magpapadala ng isang signal ng feedback pabalik sa remote upang ma-trigger ang LED.

Titiyakin ng prosesong ito ang ON / OFF na utos ng remote controller na maabot ang patutunguhan nito sa visual na kumpirmasyon.

Ang isang ON / OFF switch ay ibinibigay sa circuit ng remote controller para sa pag-iwas sa labis na pagkawala ng enerhiya habang nasa idle.

Inirerekomenda ang Arduino Nano o Arduino Pro-mini para sa pagbuo ng remote dahil nasa mas maliit na form factor na ginagawang portable.

Diagram ng Circuit:

Sa itaas ay ang kumpletong circuit diagram para sa remote control. Ang diagram ng koneksyon ng pin para sa NRF24L01 ay ibinibigay din sa parehong eskematiko.

Patayin ang remote kapag tapos ka na.

Tinatapos nito ang Remote circuit circuit.

Ang tagatanggap:

Ang circuit ng tatanggap ay binubuo ng Arduino na maaaring mapili mo, 10 kasalukuyang nililimitahan ang mga resistor na 330 ohm, 10 transistors at 10 relay ang bumubuo ng yugto ng paglabas.

Sa bawat isa sa 10 output pin ng Arduino ay konektado sa 10 relay sa pamamagitan ng risistor at transistor.

Mangyaring tiyakin na ang iyong suplay ng kuryente ay may kakayahang magbigay ng hindi bababa sa 1A ng kasalukuyang kung saan kinakailangan upang mapatakbo ang maraming relay sa isang iglap.

Ang isang 2.4 GHz transceiver module na NRF24L01 ay nagbibigay ng komunikasyon sa pagitan ng remote.

Diagram ng Circuit:

Kung nalilito ka sa mga diagram ng mga kable sa pagitan ng Arduino at NRF24L01 module, tingnan lamang ang talahanayan sa tabi ng eskematiko, pareho din ito sa remote circuit circuit.

Ang pagkakasunud-sunod ng output at output pin ay ang mga sumusunod:

Arduino PIN - Pagsunud-sunod ng output

PIN 2 - OUTPUT 1
PIN 3 - OUTPUT 2
PIN 4 - OUTPUT 3
PIN 5 - OUTPUT 4
PIN 6 - OUTPUT 5
PIN 7 - OUTPUT 6
PIN 8 - OUTPUT 7
PIN A0 - OUTPUT 8
PIN A1 - OUTPUT 9
PIN A2 - OUTPUT 10

Output Stage:

Ang output ay ipinakita lamang sa dalawang yugto ng paglabas para sa pagiging simple ng diagram. Dapat mong palawakin ito sa sampu, kung ginagamit mo ang lahat ng 10 mga channel.

Tinatapos iyon ang Tumatanggap.

Mayroon itong hanay ng teoretikal na 100 metro halos maaari itong gumana sa paligid ng 30 metro at mas mataas, maaaring mag-iba depende sa solidong hadlang sa pagitan ng remote at receiver.

Paano patakbuhin ang proyektong ito:

• I-on muna ang Receiver at pagkatapos ang Remote.

• Pindutin ang anuman sa mga pindutan sa remote nang paisa-isa.

• Kung pinindot mo ang unang pindutan ang kaukulang output ay ma-trigger, ibig sabihin, ang output 1 ay ON. Kung pinindot mo muli ang parehong pindutan sa remote, papatayin nito ang output 1 sa tatanggap.

• Nalalapat ito para sa lahat ng mga pindutan at 10 output.

• Patayin ang remote pagkatapos magamit.
