Wireless temperature and humidity sensor/One-way transmitter module/APC300
Many-to-one/star structure module combination
APC300/RF5150 ultra-low power wireless temperature measurement transmitter module
APC300/RF5150 ultra-low power wireless temperature measurement transmitter module
The APC300 (RF5150) module is an ultra-low-power micro-power transmitter module designed for wireless temperature measurement products
The module uses ultra-low-power single-chip microcomputer and high-performance low-power transmitter chip, built-in 12bits high-precision ADC, can be directly connected to various mainstream digital and analog sensors,
Such as PT1000 thermistor, DS18B20 sensor, etc.;
The user does not need to write the software of the wireless and sensor parts, and does not need additional MCU and peripheral devices, just connect the sensor directly to the corresponding tube of the module to use.

The module provides multiple channel options, and can modify various parameters such as serial port rate, transceiver frequency, transmit power, radio frequency rate, transmit interval, and sensor type online.
The working mode of the module is to collect sensor data regularly and send and receive the module directly. The transmission interval can be easily set by software and MCU. The working voltage of the module is 2.1-3.6V, which is completely battery-powered. The transmission current is only 14mA under 10mW transmission power. The current is as low as 1.5uA, and an ordinary lithium sub-battery (such as ER18505) has a working life of several to ten years.
Note: There are two types of modules: no relay and with relay. If there is no special instructions, it will default to no relay.
