By today we've seen plenty of projects that use an ESP8266 as a form of basic access control: touch a key on your smartphoné, and the door to your residence unlocks. With the strength and flexibility of thé ESP, it's a extremely easy project to pull off with minimum additional hardware. But what abóut if you want to get a little even more critical, and want to support many users?

Founded in 1971, Secura Key has pioneered, developed and manufactured a full range of products for electronic access control and radio-frequency identification. Secura Key products are known internationally for their reliability, simplicity of operation, ease of installation and ability to withstand harsh weather and extreme temperatures.
Instead than reinvent the steering wheel, you might would like to verify out the incredibly amazing ESP-RFID task. It's i9000 still structured on thé ESP8266 we all understand and love, but it combines the diminutive WiFi-enabled microcontroIler with a fine custom made PCB and some remarkably clever software to make a really expert access control program without bursting the bank. As the title implies, the system is geared towards RFID authentication and facilitates readers like as thé MFRC522, PN532 RFID, or RDM6300. Include in a stack of Mifare Vintage 1KW credit cards, and your hackerspace will be properly on the method to obtaining a brand-new door control program.
The public hardware for ESP-RFID can be bought through Tindié with or withóut an installed ESP-12F component, but as it's a fully open source project, you're also free of charge to construct your personal version if you'd like. In either occasion, the panel enables you to very easily link thé ESP up to yóur RFID viewer of selection, as properly as door sensors and of training course the doorway seals themseIves.
0n the software part of factors, ESP-RFID should end up being able to manage about 1000 special customers and their RFID cards before the relatively limited RAM and storage space of the ESP catches up with it. But if yóu've got that numerous people arriving and heading in your hackérspace, it might end up being period to up-date your systems to begin with. In addition, the project can make no guarantees about the security of the ESP-RFID code, and says that the program shouldn't be utilized for secure places. That said, you can operate ESP-RFID without an Web connection to decrease your assault surface area, at the cost of dropping NTP period synchrónization.
lf you're not managing a few hundred users and their RFID cards, one of the even more simplistic ESP8266 door locks might become even more your acceleration. We've furthermore seen related tricks taken off with thé Particle Phóton, in case you've obtained one of thosé rattling around thé components trash can.
