Ondřej Karas writes, “One year ago, I published two posts about PWM module driven by IQRF. But there is also another way, how to generate PWM signal from IQRF TR module only. Just simple use PIC peripherals. This post is based on one of Advanced examples, which is part of IQRF Startup Package.” More details […]

RFID – Wiegand2 – IQRF
Ondřej of DoItWireless writes: This post describes simple RFID reader with wireless transmission to the PC. There is used Wiegand26 protocol for communication between TR-52DA and IQRF reader. This construction would be useful for installations on places, where you are not allowed to use additional cabling.
Wireless servo controller II
Ondřej Karas of DoItWireless writes: We described simple method, how to drive modellers servo. Today, we are going to try to drive this servo from potentiometer connected to TR module ADC. It is reaction to forum thread where is discussion about airplane model control possibility. Check out the video after the break.
Wireless ADC to relay example
Ondřej Karas of DoItWireless writes: Sometimes, you need to measure analog signal and then switch something on or off according to the result. This short example shows, how to do it. Everything you need is DDC-SE-01 module as a sensor module and DDC-RE-01 as relay module. Of course you need DK-EVAL-04 or CK-USB-04 for both of […]
Temperature and humidity measurement with DHT11
Ondrej Karas of DoItWireless writes: This article describes temperature and humidity measurement with DHT11 sensor connected to TR module. Circuit diagram is very simple. You need only power supply for sensor and one wire for data line. This line has to be “pull-uped” – sensor has open colector output.
