HR-1000 Mini Power Wireless Module User’s Manual
The HR-1000 is direct-current power supply, the voltage is +5V, the typical voltage is +5V, the electric current is bigger than 35mA.The user need to order if they use 3V Power supply. The power source can share a power supply with other equipment, but must choose the power source with good ripple coefficient, and we suggest don’t use the switching power supply, if must use, please note mutual disturbance between the turn-on frequency of the switching power supply and the broadcasting station frequency. In order to prevent the breakdown of static electricity or the strong electric, when the system equipment been used, then needs to earth it reliably, at the same time must isolate the city electricity completely.
HR-1000 consists of sleeping and awaken editions, sleeping edition is current 15uA, HR-1000 sleeping function is hardware wake, hardware wake via pin5 input high level into sleeping, input low level into wake If the HR-1000 module taking sleeping function, but user does not to use sleeping function, user can make pin5 of HR-1000 connect ground.
The detailed drawing as follow:
The working state of module convert to sleeping state, need to convert SLE pin low level to high level, when the module is not working, MCU about 1ms will be into sleeping state, when HR-1000 is transmitting and receiving, HR-1000 will be into sleeping after completing data transmitting and receiving. Module convert sleeping state to working state, have to put SLE pin from high level to low level, MCU will work after several ms, in order to get stable data, user need to delay 60ms, then can transmit data.
