Item 1.01    Entry into a Material Definitive Agreement.

On March 1, 2010, Electronic Sensor Technology, Inc. (the "Registrant") received
$200,000 from Halfmoon Bay Capital Ltd in exchange for (1) a debenture bearing
an interest rate of 9% with a maturity of one year; such debenture grants
Halfmoon Bay a security interest in all of the tangible and intangible property
of the Registrant and, to the extent such property is subject to a prior lien, a
subordinate security interest and (2) a warrant to purchase 400,000 shares of
the Registrant with an exercise price of $0.02 cents per share and an expiration
date of August 31, 2012 (the "Warrant").

Halfmoon Bay currently owns approximately 55% of the outstanding common stock of
the Registrant and beneficially owns an additional 10% of the outstanding common
stock of the Registrant by virtue of the shares underlying a 9% convertible
debenture issued by the Registrant to Halfmoon Bay on March 28, 2008.  On April
10, 2009, the Registrant received $1 million from Halfmoon Bay in exchange for a
debenture bearing an interest rate of 9% with a maturity of one year. Such
debenture granted Halfmoon Bay a security interest in all of the intellectual
property of the Registrant.

A copy of the 9% debenture issued to Halfmoon Bay on March 1, 2010 is attached
hereto as Exhibit 4.1 and incorporated herein by reference.

Item 2.03    Creation of a Direct Financial Obligation.

The disclosures in Item 1.01 are incorporated into this Item 2.03 by reference.
Upon the occurrence of certain circumstances, such as default in payment or
bankruptcy of the Registrant, the principal amount of the 9% debenture held by
Halfmoon Bay, and any interest thereon, become immediately due and payable in
cash.

Item 3.02    Unregistered Sales of Equity Securities.

The disclosures in Item 1.01 as they relate to the Warrant are incorporated into
this Item 3.02 by reference. The exemption from registration under the
Securities Act of 1933, as amended, is Section 4(2). Halfmoon Bay is a
controlling shareholder of the Registrant.
