Chirp! plant watering alarm from Catnip electronics on ...

Chirp is a plant watering alarm as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. Alternatively, Chirp can work as an I2C soil moisture sensor, check out the Arduino example here. If all you need is moisture sensing, consider buying a standalone sensor ...

9/10/2019· In 2016, a novel interrogation technique for phasesensitive (Phi;)OTDR was mathematically formalized and experimentally demonstrated, based on the use of a chirpedpulse as a probe, in an otherwise directdetectionbased standard setup: chirpedpulse (CP)Phi;OTDR. Despite its short lifetime, this methodology has now become a reference for distributed acoustic sensing (DAS) …


Chirp an overview | ScienceDirect Topics

A chirp is a waveform whose frequency changes as a function of time, sweeping a given bandwidth B around the carrier frequency f c. The frequency content of such \wave is used to increase the resolution of the system by filtering accordingly the received signal (using a matched filter, conceptually similar to a crosscorrelation between the transmitted signal and the received one).

Hardly any competition for Chirp''s ultrasonic ToF sensor chips

19/12/2017· Earlier this year, Californian startup Chirp Microsystems was promoting an ultrasonic sensing development platform for wearables, to detect objects and small gestures down to millimeter accuracy. Now, the company is officially announcing two discrete ultrasonic TimeofFlight (ToF) sensors, the CH101 and CH201, with maximum sensing ranges of 1m and 5m, respectively.


Structured DeChirp for Compressive Sampling of LFM Waveforms

In this paper, we consider the dechirp process as part of the sensing matrix formulation for compressive sensing (CS), but modify the dechirp reference signal in a way that enables compressive sampling [2]. Typically, the sample rate must be matched to the bandwidth of beat frequencies produced by the dechirp process.

Chirp Wikipedia

A chirp is a signal in which the frequency increases or decreases with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spreadspectrum communications. This signal type is biologically inspired and occurs as a phenomenon due to dispersion. It is usually compensated for by …
