IoT Specialization

For specific IoT applications, we use Espressif ESP32 chips, which is very cost-effective, providing a range of I/O inputs, Bluetooth BLE and Wi-Fi. However, they are not very power efficient, so it is necessary to provide power for them. However, it offers an inexpensive way to connect the device to a local network or the Internet.

For pure battery applications we use Microchip IoT LoRa chips, Which are extremely energy efficient and suitable for long term measurements (with reasonable measurement interval). The advantage is LoRa signal coverage almost all over the country and extreme battery life, the disadvantage is the small volume of data transmitted in one packet.

In case of the requirement for control from the Internet, we operate our own cloud solution and develop electronics for communication via the Internet (including VPN data security). We produce RS-232 and RS-485 converters for communication to the "Internet".

We offer

Examples of our own development

• LoRa battery IoT module: a special LoRa battery IoT module developed for CTU. It measures air pressure (connected by a hose), water column and GPS position at regular intervals. Using the LoRa network, it transmits this data for further processing and visualization on a map. The battery life is about 2-3 years. The add-on software analyzes the data from the LoRa network, visualizes the measured values in graphs and maps and can also diagnose the LoRa transmitters used, including visualization. All this via a web application.
• RF868 MHz: Wireless control and measurement system at 868 MHz with bidirectional communication. The system includes components: relay contact, remote control with bidirectional communication, shock sensor, signal analysis module as well as temperature and humidity measurement module with extremely long battery life. The system transmits data via the main gateway to servers via LAN/Ethernet to plot graphs, generate statistics, monitor limits and send alarm messages. The gateway with extended memory has a capacity of 16 MB RAM.
• Safety system controller with GSM: The device is used to connect the outputs of several measuring systems and link them together for logical evaluation and timing. At the same time, it controls two back-up power supplies, measures the temperature in the control cabinet and can communicate and control events via GSM wall and also via HTTP commands over LAN - Ethernet. Installation in a 1U rack in a data cabinet.
• 2W Bus Tester: the 2W Bus Diagnostic Kit helps in analyzing the condition of existing wires and diagnoses whether the communication is free of interference, reflections and data is transmitted safely over the entire 2-wire bus.
• 868 MHz RF modem: development and production of a radio transmission modem for the 868 MHz band
• Development kit for Altera CPLD circuits
• Development of a 10 kHz - 1 MHz amplifier: the 4-channel amplifier is a 40 dB amplifier that is essential for measurements using the nonlinear ultrasonic spectroscopy method, but also for other applications where its specific characteristics come in handy.
• This relay card can control up to 12 devices with a maximum load of 240V/16A. Control via low voltage input terminals or via RS-232 interface.
• The 1:4:16 multiplexer is used to multiplex signal paths. The ability to control it via the serial port (RS-232, 9600-N-1) saves a lot of manual work.
• Resistance Decade: Digitally controlled resistive decade (cascade) with continuously adjustable resistance from 10 Ω to 10 MΩ, maximum current load of 1000 mA, and maximum voltage of 125 V.
• The electronics can boost the voltage to the required 28 V with a very stable waveform (no interference). The input voltage to this power supply can be in the range of 3-20 V.
• Preamplifiers: A low-noise preamplifier for acoustic emission (AE) sensors is an essential part of larger installations where signal attenuation occurs. The preamplifier gain is fixed at 40 dB/20 dB.
