Item 1.01      Entry into a Material Definitive Agreement.

On March 28, 2008, Electronic Sensor Technology, Inc. (the "Registrant") entered
into and closed a Securities Purchase Agreement with Halfmoon Bay Capital Ltd
("Halfmoon Bay"), pursuant to which, in exchange for a purchase price of
$5,500,000 paid by Halfmoon Bay, the Registrant issued (i) 86,419,753 shares of
its common stock, par value $.001 per share ("Common Stock") at a price of
$0.0405 per share (which is 90% of the closing quotation of the Common Stock on
the OTC Bulletin Board for the trading day preceding the closing date) and (ii)
a 9% convertible debenture due five (5) years from the closing date, with a
conversion price of $0.0486 (which is 120% of the price at which the Common
Stock was issued to Halfmoon Bay) in a principal amount of $2,000,000, with
interest to be paid thereon semiannually. The Registrant agreed to use, and did
use, $3,500,000 of the purchase price paid by Halfmoon Bay, in addition to
shares of its Common Stock, to extinguish the existing 8% convertible
debentures, and related accrued interest, held by Midsummer Investment Ltd.
("Midsummer") and Islandia, LP ("Islandia"), pursuant to the Conversion and
Termination Agreement among the Company and Midsummer and Islandia dated as of
February 26, 2008, which is further described in our Current Report on Form 8-K
filed with the Securities and Exchange Commission on February 27, 2008.

Pursuant to the Securities Purchase Agreement, the Registrant also agreed to use
its commercially reasonable efforts to cause director candidates recommended by
Halfmoon Bay to be nominated and elected to its board of directors, in
proportion to Halfmoon Bay's ownership.

A copy of the Securities Purchase Agreement is attached hereto as Exhibit 10.1
and incorporated herein by reference, and a copy of the 9% convertible debenture
issued to Halfmoon Bay is attached hereto as Exhibit 4.1 and incorporated herein
by reference.

Item 1.02      Termination of a Material Definitive Agreement.

On March 31, 2008, the 8% convertible debentures of the Registrant held by
Midsummer and Islandia were terminated, pursuant to the terms of the Conversion
and Termination Agreement attached as Exhibit 10.2 to, and further described in,
our Current Report on Form 8-K filed with the Securities and Exchange Commission
on February 27, 2008, which description is 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% convertible
debenture held by Halfmoon Bay, and any interest thereon, become immediately due
and payable in cash.

Item 3.02      Unregistered Sales of Equity Securities.

On March 28, 2008, pursuant to the Securities Purchase Agreement with Halfmoon
Bay, the Registrant issued 86,419,753 shares of Common Stock at a price of
$0.0405 per share and the 9% convertible debenture with a conversion price of
$0.0486 to Halfmoon Bay. On March 31, 2008, pursuant to the Conversion and
Termination Agreement with Midsummer and Islandia, the Registrant issued
6,685,714 shares of Common Stock to Midsummer and 3,714,286 shares of Common
Stock to Islandia.

The issuances of the shares of Common Stock to Halfmoon Bay, Midsummer and
Islandia, and the 9% convertible debenture to Halfmoon Bay were unregistered.
Such issuances were in reliance upon the representations of Halfmoon Bay,
Midsummer and Islandia that each is an "accredited investor", as defined in Rule
501(a) under the Securities Act of 1933, as amended, or a "qualified
institutional buyer", as defined in Rule 144A(a) under the

Securities Act, and is not required to be registered as a broker-dealer under
Section 15 of the Securities Exchange Act of 1934, as amended.

The disclosures in Item 1.01, and our Current Report on Form 8-K filed with the
Securities and Exchange Commission on February 27, 2008 are incorporated into
this Item 3.02 by reference.

Item 5.01      Changes in Control of Registrant.

As a result of the transaction described in Items 1.01 and 3.02, which are
incorporated into this Item 5.01 by reference, Halfmoon Bay will own
approximately 55% of the outstanding Common Stock of the Registrant, and will
beneficially own an additional 10% of the outstanding Common Stock of the
Registrant by virtue of the shares underlying its 9% convertible debenture.
Immediately prior to such transaction, no single shareholder of the Registrant
owned a majority of the outstanding shares of the Registrant, and the
Registrant's largest owners of outstanding shares were L&G Resources (1994),
Inc. (wholly owned by Land & General Berhad),owning approximately 16%; TC Lim,
LLC (wholly owned by Teong Lim, a director of the Registrant), owning
approximately 9%; 3 Springs, LLC (wholly owned by Francis Chang, a director of
the Registrant), owning approximately 7%; and Midsummer and Islandia,
collectively owning approximately 8%.

A copy of the press release issued on March 31, 2008 announcing the foregoing
transactions is attached hereto as Exhibit 99.1.
