We are

Twenty-first century robotics and sensing technologies have the potential to solve problems as old as civilization itself.

Symappsys draws the way to apply modern technology for the well-being of people and nature.

We aim at areas where the greatest benefit of society and individuals can be seen. Environment and food production are key factors for our future. By investing our knowledge and experience, we are trying to respond to these challenges, which are waiting for our children too.


In addition to their functionality, intelligent devices must also have both caracteristics such as mobility, energy efficiency and autonomy. That's why we've come up with a concept in which any smart sensor can become a smart gateway

This approach allows us to make devices even cheaper and more flexible. The backbone of our smart devices is the ESP8266 microcontroller

“Our perspective is that cost of both the sensors and devices is approaching free and the size is approaching invisible. Our perspective is literally everything will have IOT technology at some point,”

— James Bailey, Accenture

With the use of this microcontroller, our smart devices combine features that are characterized by the controller itself

32-bit Tensilica Processor

Tensilica L106 32-bit RISC processor, which achieves extra-low power consumption and reaches a maximum clock speed of 160 MHz.

High Durability

ESP8266EX is capable of functioning consistently in industrial environments, due to its wide operating temperature range.

Power-Saving Architecture

Engineered for mobile devices, wearable electronics and IoT applications, ESP8266EX achieves low power consumption with a combination of several proprietary technologies.


ESP8266EX is integrated with a 32-bit Tensilica processor, standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules.

Low power communication protocol

ESP-Now enables multiple devices to communicate without using Wi-Fi. The protocol is similar to the low power 2.4GHz wireless connectivity that is often deployed in wireless mice.

Long-range communication protocol

Semtech’s LoRa transceivers feature a long-range wireless modem that provides ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption.
