Hello, I have a question regarding RF modules from AUREL, HOPE etc....
HOPE MICROELECTRONICS HM-TRS868
AUREL 650201280G
How can sensors be connected to them
have outputs, example from aurel:
1. ANTENNA
2. GND
5. GPIN0 / ADC0 / LIMITSWITCH_OPEN
6. GPOUT0 / MOTOR_UP / PWM
7. LEARN (Input for learning procedure, pull-up is already provided. A button towards
GND should be used)
8. UART RX (Input for module)
9. LED (Output for learning confirm. A led towards GND with resistance should be
used)
10. UART TX (Output for module)
11. VCC (+3V or +5V)
12. GND
13. ENABLE (High: ON – Low: OFF, with built-in pull-down resistor). This pin can be
driven by an external microcontroller, with no need for dedicated regulators or
transistors to break module power-supply
14. GPIN1 / ADC1 / LIMITSWITCH_CLOSE
15. GPOUT1 / MOTOR_DOWN
And can more than one sensor be connected to them, as they have an Atmega? Can they be connected directly or is something else necessary?
I want them to transmit the readings of the various sensors over a distance.
