We are a team of eleven students of electronic and telecommunications engineering in University of Aveiro. As a company our team strongly believes in a better future. We aim to get people closer and closer. We want people to feel free to go everywhere and at any time. So, we are building a product to fit everywhere. Our mission is to reinvent the pole and build a sense of security and comfort for the people. Nowadays, when we think about the future, we tend to think in new solutions. Our team decided to look around and improve what already exists. We know that bicycles will be for a very long time a reliable option to travel. We have also decided to do a product that holds on low-cost materials and fast repair. One other idea that our company wants to take on is renewable energies. Our difficulties are the great massification of all existing poles at a lower cost of production, the vandalism that can be practiced and the unfavourable weather that can lead to uncharged batteries. As a company we intend to operate in a vast market such as lighting. We intend to spread our product through construction companies, IOT, telecommunications companies and municipals. We understand there are a wide range of opportunities to our idea so after analysing our market opportunities we decided to mainly focus on University Campus to start off. We want to prove our concept so let us start at home. Our site, to check all the ongoing of our project!! http://detpole.web.ua.pt/

LoRa or Long Range wireless data telemetry is a technology pioneered by Semtech that operates at a lower frequency than NRF24L01 (433 MHz, 868 MHz or 916 MHz agains 2.4 GHz for the NRF24L01) but at thrice the distance (from 3000m to 8000m).You can find E32 here AliExpress (433MHz 3Km) - AliExpress (433MHz 8Km) - AliExpress (868MHz 3Km) - AliExpress (868MHz 8Km) - AliExpress (915MHz 3Km) - AliExpress (915MHz 8Km)You can find here AliExpress (433MHz 4Km) - AliExpress (433MHz 10Km)You can find the adapter for SMD modules on We are going to test E32-TTL-100 and E22. E32It is a wireless transceiver module, operates at 410 441 MHz based on original RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. The module adopts LORA spread spectrum technology.The module features FEC Forward Error Correction algorithm, which ensure its high coding efficiency & good correction performance. In the case of sudden interference, it can correct the interfered data packets automatically, so that the reliability and transmission range are improved correspondingly. But without FEC, those da te packets can only be dropped.And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interference, while improving the reliability & transmission efficiency.E22It is a wireless transceiver module, operates at 410 493 MHz based on original RFIC SX1268 from SEMTECH, transparent transmission is available, TTL level.

In this project, we will create an infrared remote control for your TV, cable box, DVR, Blu-ray, or another similar consumer electronic device. The remote control is operated by a webpage interface. The Raspberry Pi serves the webpage over your local Wi-Fi network. You can access it on your PC, laptop, tablet, or phone as long as it is connected to your local Wi-Fi network.You can learn more about this project at https://github.com/cyborg5/qtpyhat and a full learning guide will be available on Adafruit.com.

The original ISPINDEL PCB is CHERRYPHILIPYou can find instructions, video tutorials on youtube (key search iSpindel). THANKS ALL USERS for that.The cherryphilip 4.1 PCB for the iSpindel, few minor improvements introducing on this version. Here main features:On the front , I moved of few mm the thermal sensor device outside battery area. To avoid possible short circuit due to pins that could touch the body of battery or ti have fake measurements.On the bottom edge there is a change as well. I indroduced a specific form just to touch the bottom petling.During the design i used a Sansung 30Q battery with 48gr weitght incorporates a fixeble battery holder allowing you to have your iSpindel to 25° degrees in pure water. However, there are some battery with different weights that can changes the final balance. No worries, iSpindel works fine with balance between 20° to 30°Sincerely,cherryphilip

So I was needed to control almost 200+ relays using one microcontroller and during research I found out that best way to do it is by using a GPIO Expander module but I wanted to have some simpler solution which should be both small and compact. Now if you worked with addressable RGB LEDs or neopixels you already know that we can control lots of such LEDs by just using one output pin. There is a chip inside each of the LEDs which can control 3 outputs, Red, Green and Blue LED in this case. It reads the data coming from the microcontroller, set it's outputs according to the given instructions and pass the rest of the code to the next IC. This way we can daisy chained as many of them as we want. I just wanted to impliment the same principle for any output devices in general, such as relays, to control even bigger loads.

Don't populate JP1 jumper until you regulate this module output voltage. Power on J1 with a voltage between 8 and 28 Vdc, be carefull about polarity. Then regulate output to 5Vdc with potentiometer on module. After checked that voltage, you can populate Jumper to supply power to all board.External PS 5VdcIf you want to supply this board with 5Vdc directly, don't use MP1584 module and instead solder a jumper cable between Vin+ and Vout+. Power supply input on J1 too.USB PS to ESP32You can supply 5V throught USB from ESP32 too, but you are limited to 500mA from a computer, and 1A from an external 5V power supplyFeatures:1 analog input for Sensor, like 5Vdc pressure sensor (P3), populate R4=10K and R5=20K to have a voltage divider of 1.53 digital input for Rotary Encoder or Switches (P6)2 extra Input/Outputs for sensores or 2-relay Module (P8)4 Input/Outputs for 4-relay Module (P5)1 output for buzzer module or you can populate R6=10K, Q1=2N7000/2N7002 Mosfet transistor channel N, BZ1=5Vdc buzzer - diam=12mm1 UART0 comm port (P9), you can interface it with a USB/RS-232 TTL module to communicate with PC (3.3V compatible)1 One Wire port, mostly for read temperature sensors like DS18B20, you can connect in parallel. Populate R1=4.7K for less than 3 sensors.1 extra Input/Outputs for sensores or 1-relay Module (P1)1 OLED I2C connection for 4 or 7 pin 0.96 module (P4)1 extra I2C port, for display LCD or ADC module ADS1115 (P11). You can select between 5 and 3.3V for this connector, soldering JP2 between 1-2 or 2-3 pins. Populate R2=4.7K and R3=4.7K if your I2C device doesn't have it.
