1. OverviewWTN5 series is 4-bit controller. Now there are three kinds of chip WTN5055, WTN5025, WTN5085(voice length is 55s, 25s, 85s respectively), WTN5055, WTN5085 have been put into market. Next WTN5025 will come soon. Audio sample rate is up to 44.1kHz maximally,16-level volume control. Two audio output modes: PWM output and DAC output. Accurate +/-1% internal shock, no need to have external shock, ultra-low power consumption in standby mode. 2. Functions☆Working voltage: 2.2V~5.5V.☆In standby mode, quiescent current less than 1uA.☆Accurate+/-1% internal shock, also providing external shock for speed governing, with the function of low voltage reset(LVR=1.8V), watchdog timekeeping and I/O reset.☆PWM audio output, able to drive...
IntroductionHuman body induction is a kind of technology that infrared pyroelectric principle is used to induce the body activity information. When a person enters the sensor's induction range, the information will be accurately identified and detected, which is like cat's eyes, not rely on the light. Even in the dark environment, it can work normally, overcoming the deficiencies of the light induction.PowerSound V9.00 infrared sensor ceiling speaker adopts WT2003S-16S voice chip, support DIY function, MP3 audio format, high-power speaker. When detect people passing by, the device will play voice immediately. Use can replace the voice content to have different sound effect. Features☆Infrared pyroelectric induction. ☆Can replace voice files, connected to computer...
WTR030 sound recording ic module has long recording distance, good sound quality, can directly drive 8Ω/0.5W speaker. Support 4Mbit~64Mbit flash. Following functions can be realized: key control, long press to record, short press to record/ play/ stop. Built in SPI-Flash, with microphone.WTR030-M01 recordable voice module is built in standard SPI communication. Can control multiple voice recording and playback through SPI. Features☆Working voltage: 2.8V~5.2V.☆Automatically into sleep mode when not working.☆Support 4Mbit-64Mbit SPI Flash.☆Hold to record, press to record, play, low level keep loop playback.☆Standard SPI communication.☆Record/ play mode: separate voice recording or separate prerecorded voice play.☆Prerecorded voices stored on SPI Flash....
